Can a compound be 2 elements?
A compound is a chemical substance made up of two or more elements.
Is 2 or more elements a compound?
chemical compound, any substance composed of identical molecules consisting of atoms of two or more chemical elements.
What two elements make up a compound?
When two or more atoms of different elements join together, we call it a compound. All compounds are molecules, but not all molecules are compounds. That is because a molecule can be made up of two atoms of the same kind, as when two oxygen atoms bind together to make an oxygen molecule.

Water, carbon dioxide and table salt are some examples of compounds.
What two elements make up water?
A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom.
What elements make up?
In chemistry, an element is a pure substance consisting only of atoms that all have the same numbers of protons in their nuclei. Unlike chemical compounds, chemical elements cannot be broken down into simpler substances by any chemical reaction.
How can two elements form two different compounds?
If two elements combine in a different ratio, the result is a different compound. In other words, the same compound will always form from the same elements in the same ratio.
How are the compounds formed?
Compounds occur when two or more atoms combine into a pure substance. These can be broken down into their constituent atoms. In chemical reactions the atoms of the reactants interact to form new substances. The reacting species are called reactants, and those produced are products.
What is formed when 2 or more elements combine?
Elements can be chemically combined into compounds, therefore, a compound consists of two or more elements combined, in definite proportions, by chemical means. Compounds may be formed by combining atoms of their constituent elements by ionic bonds or by covalent bonds.
When two elements are combined they are called?
A combination of two or more elements chemically combined is a compound .
Can you have more than one compound made of the same two elements?
The law of multiple proportions states that whenever the same two elements form more than one compound, the different masses of one element that combine with the same mass of the other element are in the ratio of small whole numbers.
Can compounds be made from two metals?
Although there definitely is such a thing as metallic bonding, when we combine two or more metals, the result is a mixture. This means that there is no definite proportion to the combination, the way there is for a compound.
What is example of element and compound?
Compound | Symbol | Elements in the compound (and state at room temp) |
---|---|---|
Water | H2O | Hydrogen (gas) oxygen (gas) |
Carbon dioxide | CO2 | Carbon (solid) oxygen (gas) |
Magnesium oxide | MgO | Magnesium (solid) oxygen (gas) |

What 2 elements make up the sun?
Oxygen: A critical element
Despite the controversy, everyone agrees on the basics: The sun consists mainly of hydrogen and helium, the two lightest elements. It generates energy at its center through nuclear reactions that convert hydrogen into helium.
Is carbon dioxide made of 2 elements?
Carbon dioxide, CO2, is a chemical compound composed of two oxygen atoms and one carbon atom.
What elements make up salt?
Chemically, table salt consists of two elements, sodium (Na) and chloride (Cl). Neither element occurs separately and free in nature, but are found bound together as the compound sodium chloride.
How many compounds are there?
Globally, more than 350,000 chemical compounds (including mixtures of chemicals) have been registered for production and use. A compound can be converted to a different chemical substance by interaction with a second substance via a chemical reaction.
What is an element What is a compound?
An element is a material that consists of a single type of atom. Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds.
What makes an element an element?
An element is a substance that cannot be broken down into any other substance. Every element is made up of its own type of atom. This is why the chemical elements are all very different from each other. Everything in the universe contains the atoms of at least one or more elements.
How are compounds formed name two examples of a compound?
When two elements are combined through a chemical reaction then a compound forms. For example water is a compound formed from the combination of hydrogen and oxygen. 2H2 + O2 → 2H2O. Complex molecules such as proteins are formed by a series of reactions involving elements and simple compounds.
How is a ionic compound formed?
An ionic compound is a compound that is formed by ionic bonding. Ionic bonding occurs through a process called electron transfer, where one atom gives electrons to another.
How are compounds formed and separated?
An impure substance made from different elements or compounds mixed together that are not chemically joined. Mixtures can usually be separated by physical techniques such as filtering and distillation . Air is a mixture that contains the elements nitrogen, oxygen and argon, and also the compound carbon dioxide.
Which substance is a compound?
A compound is a substance that contains two or more elements chemically combined in a fixed proportion. The elements carbon and hydrogen combine to form many different compounds. One of the simplest is called methane, in which there are always four times as many hydrogen particles as carbon particles.
Is molecule and compound same?
A molecule is formed when two or more atoms of an element chemically join together. And a compound is a type of molecule, in which the types of atoms forming the molecule are different from each other.
What are 5 examples of a compound?

- Carbon dioxide (CO2)
- Sodium bicarbonate (baking soda – NaHCO3)
Are made up of 2 or more elements or compounds that haven’t been chemically combined together?
A mixture contains two or more different substances that are not chemically joined together. The different substances in a mixture can be elements and/or compounds.
Are all compounds made up of molecules?
Molecule is the general term used to describe any atoms that are connected by chemical bonds. Every combination of atoms is a molecule. A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds.

How many elements are there?
At present, 118 elements are known to us. All these have different properties. Out of these 118, only 94 are naturally occurring. As different elements were being discovered, scientists gathered more and more information about the properties of these elements.
Do 2 metals make an ionic compound?
Ionic compounds generally form from metals and nonmetals. Compounds that do not contain ions, but instead consist of atoms bonded tightly together in molecules (uncharged groups of atoms that behave as a single unit), are called covalent compounds. Covalent compounds usually form from two nonmetals.
Can two metal elements bond?
Answer and Explanation: No. Two different elements, even if both are metals, cannot form a metallic bond together.
How do you add elements to a compound?
Elements combine to form chemical compounds that are often divided into two categories. Metals often react with nonmetals to form ionic compounds. These compounds are composed of positive and negative ions formed by adding or subtracting electrons from neutral atoms and molecules.
Is the Sun fire?
Answer: The Sun does not “burn”, like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core.
Will the Sun ever burn out?
But in about 5 billion years, the sun will run out of hydrogen. Our star is currently in the most stable phase of its life cycle and has been since the formation of our solar system, about 4.5 billion years ago. Once all the hydrogen gets used up, the sun will grow out of this stable phase.
Is there uranium in the Sun?
The same cloud of enriched material that formed the Sun also formed Earth and the other planets. Thus, the same naturally occurring elements that can be found on Earth, up to and including elements as heavy as uranium, are also present in the Sun.
