Do all minerals have the same chemical composition?
All minerals have a specific chemical composition. The mineral silver is made up of only silver atoms and diamond is made only of carbon atoms, but most minerals are made up of chemical compounds. Each mineral has its own chemical formula. Halite, pictured in the Figure 2.2 above, is NaCl (sodium chloride).
What is the chemical composition for all minerals?
CHEMICAL GROUP | EXAMPLES | |
---|---|---|
CARBONATE minerals | Calcite, CaCO3; Dolomite, CaMg(CO3)2 | |
SILICATE minerals | ||
STRUCTURAL SUBGROUPS OF THE SILICATES | Olivine, (Mg,Fe)2SiO4; Garnet, (Fe,Mg,Ca)3Al2Si3O12 | |
Pyroxene, e.g., Augite, Ca(Mg,Fe)Si2O6 |
Do minerals have a chemical composition?
“A mineral is a naturally occurring chemical compound, usually of crystalline form and abiogenic in origin. A mineral has one specific chemical composition, whereas a rock can be an aggregate of different minerals or mineraloids.
Does a mineral have to have a unique chemical composition?
Each mineral has its own unique chemical formula. For example, the mineral hematite has two iron atoms for every three oxygen atoms. The mineral magnetite has three iron atoms for every four oxygen atoms. Many minerals have very complex chemical formulas that include several elements.
How minerals are classified based on its composition?
Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides).
Are all elements minerals?
The words “element” and “mineral” do not mean the same thing. A chemical “element” is a material containing only one kind of atom. In some cases, elements can form minerals, but they don’t have to. For example, hydrogen is an element, but it is not a mineral because it is neither crystalline nor a solid.
Why do minerals rarely exhibit pure chemical compositions?
Based on the brief discussion of chemistry and chemical bonding in chapter 3, why do minerals rarely exhibit pure chemical compositions (100% always the same chemical composition)? Certain elements can substitute for others of similar size without changing the minerals’ internal structure.
Why do minerals have definite chemical composition?
Definition of a Mineral:
With a definite chemical composition (every time we see the same mineral it has the same chemical composition that can be expressed by a chemical formula). and a characteristic crystalline structure (atoms are arranged within the mineral in a specific ordered manner).
Do minerals have a specific predictable chemical composition?
Minerals have a specific, predictable chemical composition. Minerals can be liquid, solid, or glass. Minerals can be identified by characteristic physical properties. Minerals have a specific, internal, crystalline structure.
Do minerals have chemical properties?
Minerals can be identified using a number of properties. These include physical and chemical properties such as hardness, density, cleavage and colour, crystallography, electrical conductivity, magnetism, radioactivity and fluorescence.
Can the chemical composition of a single mineral vary?
The chemical composition of some minerals can vary, but only if the amounts of elements in them vary.
Are all solid materials minerals?
Solid: Minerals are solids at room temperature. Materials in the liquid or gas state at room temperature are not minerals. Not all solids, however (e.g., coal), are minerals.
How many chemical properties do minerals have?
Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage. Crystal form, cleavage, and hardness are determined primarily by the crystal structure at the atomic level.
Are all minerals naturally made?
A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.
Do all minerals have the same crystalline structure?
Minerals are inorganic, naturally occuring substances that have crystalline structures. So it is a prerequisite to be a crystal in order to be a mineral. All minerals, therefore, form crystals.
Why are minerals considered inorganic substances?
A mineral is an inorganic substance. It was not made by living organisms. Organic substances contain carbon. Some organic substances are proteins, carbohydrates, and oils.
Which mineral is also an element?
Students learn about uses of minerals by lecture and internet. BACKGROUND: Elements and compounds are the building blocks of minerals. Minerals made of only one element are called NATIVE minerals (i.e., silver, gold, mercury, copper).
What are the many properties that minerals can have?
Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.
Which of the following is not a mineral characteristic?
The correct answer is They are inexhaustible.
What are the chemical classification of minerals?
In this system, minerals are classified into eight main mineral groups based on chemical composition. These classes are: native elements, silicates, oxides, sulfides, sulfates, halides, carbonates, phosphates, and mineraloids.
How many classified minerals are there?
Chemical Composition
Of these nine, only Silicates had subgroups: Nesosilicates, Sorosilicates, Cyclosilicates, Inosilicates, Phyllosilicates, and Tectosilicates. Over the years, the classification system has grown as scientists’ understanding of minerals increases. Today, there are 78 recognized mineral classes.
Are all minerals compounds of more than one element?
Atoms and Compounds Each element is made of only one kind of atom. An atom, as you may recall, is the smallest part of an element that has all the properties of that element. Like all other substances, minerals are made up of atoms of one or more elements.
What is the difference between a chemical element and a mineral?
The difference between mineral and element is that a mineral is a naturally occurring, inorganic compound that we can breaks down into simpler structure via chemical processes whereas an element is a substance that cannot be converted into further simpler structures via any ordinary chemical process.
Are minerals compound or mixture?
While most minerals are compounds of two or more elements, some minerals are made up of a single element. Gold, silver and copper are called native elements and occur in nature in relatively pure form. The vast majority of minerals are compounds or mixtures of elements. These mixtures are consistent.
Do rocks have a definite chemical composition?
A rock is a naturally occurring aggregate of minerals and/or mineraloids. Rocks do not have a definite chemical composition.
Do rocks have a specific chemical composition?
Rocks do not have a definite chemical composition whereas minerals do. Sometimes a rock may contain organic remains in it. A mineral, on the other hand, will never have any organic material present within it.
Are minerals homogeneous or heterogeneous?
mineral, naturally occurring homogeneous solid with a definite chemical composition and a highly ordered atomic arrangement; it is usually formed by inorganic processes.
Why minerals have different physical and chemical properties?
Breaking a mineral breaks its chemical bonds. Since some bonds are weaker than other bonds, each type of mineral is likely to break where the bonds between the atoms are weaker. For that reason, minerals break apart in characteristic ways.
What is a chemical property of a mineral?
The chemical properties comprise chemical formula and the proportion of elements in the purest form of the minerals.
What is predictable chemical composition?
“A mineral is an element or chemical compound that is normally crystalline and that has been formed as a result of geological processes” (Nickel, E. H., 1995). “Minerals are naturally-occurring inorganic substances with a definite and predictable chemical composition and physical properties.” (O’ Donoghue, 1990).
What does it mean to have a specific chemical composition?
Chemical composition means the name, percentage by weight, and chemical identification of each compound in an additive.
Which mineral property is the least reliable for identifying a mineral?
The color test is the least reliable test because many different minerals have similar colors. A similar test to color is the streak test. The streak test matches the color of the mineral’s powder. Interestingly, the mineral color and the streak color are often different.
Which rock is usually composed of several minerals?
It is usually composed primarily of the minerals quartz, feldspar, and mica. When granite is subjected to intense heat and pressure, it changes into a metamorphic rock called gneiss. Slate is another common metamorphic rock that forms from shale.
What is the name of minerals that have no commercial value?
As generally used, gangue minerals have no commercial importance in a particular period of time, possibly becoming ore minerals at a later date. They are commonly silicates, carbonates, or fluorides, more rarely sulfides.
Is a mineral solid yes or no?
Once again, a mineral is a naturally occurring inorganic solid, with a definite chemical composition, and an ordered atomic arrangement!
Are all rocks minerals?
All rocks contain one or more minerals. Rocks and minerals are mined to help make things around us, from the large stone slabs used in buildings to the tiny pieces of metal in phones and jewelry.
Is a mineral has definite chemical composition Brainly?
But can you say what a mineral really is? A mineral is a naturally occurring inorganic solid, with a definite chemical composition, and an ordered atomic arrangement.
Are minerals living or nonliving?
A mineral is a solid, nonliving substance found in nature.
Is a mineral has definite chemical composition yes or no?
A Mineral is defined as an inorganic, naturally occurring, homogenous solid, with a definite chemical composition, and ordered (crystalline) atomic structures.
Do all minerals have cleavage?
Not all minerals have cleavage. A cleavage represents a direction of weakness in the crystal lattice. Cleavage surfaces can be distinguished by how they consistently reflect light, as if polished, smooth, and even.
Does every mineral have a definite and a fixed composition explain?
Explain. Yes, every mineral has a definite and fixed composition. Minerals are widely distributed in the earth’s crust in the form of oxides, carbonates, sulphides, sulphates, nitrates, etc. These minerals are formed as a result of chemical changes taking place during the formation of the earth.
Are minerals organic or inorganic compounds?
Minerals are inorganic molecules also called elements and are derived from the earth. Inorganic minerals can be incorporated into living tissue (organic) but eventually return to the earth in the inorganic form when excreted by the animal, or as ash once the animal is buried or cremated.
What is the difference between inorganic and organic minerals?
Put simply, organic trace minerals are those whose metal is chemically bonded to a molecule-containing carbon. Inorganic minerals are relatively easy to produce, inexpensive to administer and are fed as a baseline portion of an animal’s diet.
Are minerals inorganic nutrients?
Minerals are inorganic substances in our foods. Major minerals are needed in amounts greater than one hundred milligrams daily, while trace minerals are needed in amounts less than one hundred milligrams. The availability of any mineral in a food is influenced by the body’s ability to absorb it.
Can minerals have one element?
A mineral is a solid, inorganic, naturally occurring, crystalline substance with a fixed chemical composition. Diamond is pure carbon, so it is a mineral made of only one element. On the other hand, calcite is a mineral which contains carbon, as well as calcium and oxygen.
Can minerals be compounds?
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form. The geological definition of mineral normally excludes compounds that occur only in living beings.
Can a mineral contain organic material?
An organic mineral is an organic compound in mineral form. An organic compound is any compound containing carbon, aside from some simple ones discovered before 1828.
Is organic a characteristic of a mineral?
Minerals don’t belong to any class of organic compounds, which include substances such as carbohydrates, proteins and fats made by living things. Almost all known minerals come from inorganic processes — activities that living things cannot carry out.
Why do minerals rarely exhibit pure chemical compositions?
Based on the brief discussion of chemistry and chemical bonding in chapter 3, why do minerals rarely exhibit pure chemical compositions (100% always the same chemical composition)? Certain elements can substitute for others of similar size without changing the minerals’ internal structure.
What is the same about all minerals in the silicate group?
What is the same about all minerals in a silicate group? What is different about them? All silicate contain a silica tetrahedron, but to create the wide variety of silicate minerals, this pyramid-shaped structure is often bound to other elements.
Why are minerals considered matter?
Why are minerals considered matter? They have mass and take up space. Of the three kinds of substances that make up matter in nature, which one forms most minerals? A mineral sample is nothing but the element sulfur.
Which is not a way a mineral can be identified?
Unfortunately, you can rarely identify a mineral only by its color. Sometimes, different minerals are the same color. For example, you might find a mineral that is a gold color, and so think it is gold. But it might actually be pyrite, or “fool’s gold,” which is made of iron and sulfide.
Which statements describes one feature of a minerals definite chemical composition?
Which common item is made from copper? Which statement describes one feature of a mineral’s definite chemical composition? It always contains certain elements. Which characteristic involves cleavage and fracture?
