What make up molecules?
Molecules are made up of one or more atoms. If they contain more than one atom, the atoms can be the same (an oxygen molecule has two oxygen atoms) or different (a water molecule has two hydrogen atoms and one oxygen atom). Biological molecules, such as proteins and DNA, can be made up of many thousands of atoms.
Do all elements have molecules?
1 Answer. Not all elements have molecules, except elements like oxygen, nitrogen and chlorine that have diatomic molecules O2, N2 and Cl2 respectively.
Are elements made up of atoms or molecules?
Because like all things in the world, elements and molecules are both made of atoms. You know elements are all the different types of atoms on the periodic table. Molecules are what you get when those atoms are combined. Unlike elements, molecules can be made from the same or different elements.

What make up an element?
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.
Is chemistry made up?
Chemistry is the study of the composition, structure, properties and reactions of matter. Everything is made of chemicals. This includes the whole Earth – all matter in it and on it is made of chemicals.
What makes a molecular compound?
A molecular compound consists of molecules whose formula represents the actual number of atoms bonded together in the molecule. The atoms are joined to give a definite shape which is defined by the angles between the bonds and by the bond lengths.
Can an element also be a molecule?
Some elements exist naturally as molecules. For example, hydrogen and oxygen exist as two-atom molecules. Other elements also exist naturally as diatomic molecules—a molecule with only two atoms (Table 5.4.
Can you make a molecule?
Sometimes, if you want something made right, you’ve just got to make it yourself. That could certainly be the case when using molecules to construct microscopic devices such as medication-delivering nano-robots.
What three particles make up the atom?
Atoms are composed of smaller particles known as protons, neutrons, and electrons.
What is a molecular element?
Molecular elements are the chemical species that has at least two atoms of the same chemical element bonded to each other via chemical bonding. These are different from chemical compounds because a chemical compound contains two or more atoms of different chemical elements.
What is molecular substance?
Definition of Molecular Substances
It’s a molecular substance, which is a substance with two or more atoms, the smallest units of matter, joined together by a covalent bond. A covalent bond is the link created through the sharing of electrons that holds these atoms together.
What are simple molecules?
Simple molecules contain only a few atoms held together by covalent bonds . An example is carbon dioxide (CO 2), the molecules of which contain one atom of carbon bonded with two atoms of oxygen.
How are ions formed?
Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the …
How do atoms make up elements?
All elements are made up of atoms. ➢ Atoms are made up of protons, neutrons, and electrons. Two different kinds of atoms can combine to form a compound. A molecule is a combination of atoms that cannot be broken apart while still retaining the same properties as the larger substance that it is a part of.
What are atoms and molecule?
A tiny particle of a chemical element is called an atom, which may or may not exist independently. Molecules refer to the group of atoms that the bond binds together, representing the smallest unit in a compound. Two or more identical or distinct atoms are chemically bonded.

All minerals have a definite chemical makeup. A few minerals are made of only one kind of element. Silver is a mineral made only of silver atoms. Diamond and graphite are both made only of the element carbon.
Why chemistry is called the science of atoms and molecules?
Chemistry is called the Science of Atoms and Molecules. Chemistry deals with the composition, structure and properties of matter. These aspects can be best described and understood in the terms of basic constituents of matter : Atoms and Molecules. That is why chemistry is called the science of Atoms and molecules.
How many elements make up things we love?
There are 92 elements that make up the things that we love. The symbol for potassium on the periodic table is K.
Is molecule and element same?
Molecule is a substance with two or more atoms bonded together such as the oxygen humans breathe (O2). Elements are pure substances made up of all the same atoms such as gold (Au), hydrogen (H), and oxygen (O).
Why do some elements exist as molecules?
Molecular Elements
There are many substances that exist as two or more atoms connected together so strongly that they behave as a single particle. These multi-atom combinations are called molecules. A molecule is the smallest part of a substance that has the physical and chemical properties of that substance.
Is a compound a molecule?
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.
Can we create molecules from atoms?
When two or more atoms link up, they create a molecule . A molecule of water is made of two atoms of hydrogen (H) and one atom of oxygen (O). The molecular mass is the sum of the masses of all the atoms in the molecule. A collection of molecules is called a compound.
How are molecules put together?
https://www.youtube.com/watch?v=XCBazptfyJg
What are new molecules?
A new molecular entity (NME) is a drug that contains an active moiety that has never been approved by the FDA or marketed in the US.
Which of the following makes up a molecule of water?
Atoms join together to form molecules. A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom.
How are simple molecules formed?
When a few atoms combine and are held together by a covalent bond, simple molecules are formed. Therefore, simple molecules are a group of atoms held together by covalent bonds. A basic structure of an atom is that it has a nucleus and energy levels made of orbiting electrons.
How are simple molecules made?
Simple molecules are made of just one or two elements and a few atoms. Molecules are held together by chemical bonds. Bonds form so that the outer electron shell of atoms obey the octet rule, giving each atom a complete stable outer shell of eight electrons.
Which of the following particles make up atoms?
1 Answer. Protons, neutrons, and electrons.
What subatomic particles make up most atoms?
Subatomic particles include electrons, the negatively charged, almost massless particles that nevertheless account for most of the size of the atom, and they include the heavier building blocks of the small but very dense nucleus of the atom, the positively charged protons and the electrically neutral neutrons.
How do atoms molecules and extended structures make up substances?
Atoms form molecules that range in size from two to thousands of atoms. they may be extended structures with repeating subunits (e.g., crystals). phenomena can be observed at various scales using models to study systems that are too large or too small.
How do I know if an element is a molecule?
https://www.youtube.com/watch?v=pSJeMJaCkVU
How do you find the molecules of an element in a compound?
Explanation: Determine the mass of the substance, and its molar mass. Divide the given mass by its molar mass to get moles, then multiply times 6.022×1023molecules1mol .
Do elements and compounds exist as molecules and why?
All elements and compounds do not exist as molecules. Noble gases for example do not exist as molecules.
Why do elements become ions?
Ions are formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells. When they lose electrons, they become positively charged and are named cations. When they gain electrons, they are negatively charged and are named anions.
Why do elements combine to form compounds?
A compound is a unique substance that forms when two or more elements combine chemically. Compounds form as a result of chemical reactions. The elements in compounds are held together by chemical bonds. A chemical bond is a force of attraction between atoms or ions that share or transfer valence electrons.
Are all atoms ions?
Ions are atoms or molecules that have gained or lost one or more of their valence electrons and therefore have a net positive or negative charge. An atom can be an ion, but not all ions are atoms.
Atoms can bond together into groups and form a molecule. If the molecule contains atoms of different types bonded together, we call it a compound. For example, two hydrogen atoms and one oxygen atom bonded together creates the compound water.
How are atoms different molecules?
Atoms are single neutral particles. Molecules are neutral particles made of two or more atoms bonded together.
How are molecules represented?
Molecules can be represented with a chemical formula which shows the types of atoms in the molecule, and, uses subscripts, ti show how many of each type of atom is present.
Do molecules make up cells?
Atoms make up molecules; molecules make up cells; cells make up tissues; and two or more kinds of tissues working together make an organ. An organ is a part of the body that performs a specialized physiologic function.
How many atoms make molecules?
molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.
Are atoms molecules?
A molecule is made up of atoms bonded together. So, while an atom is its own separate entity, a molecule is what you get when those atoms bond together. These might be the same elements, such as two oxygen atoms bonded together (O2), or it might be different atoms bonded together like water (H2O).
How are materials made up of particles?
All matter is composed of tiny indivisible particles too small to see. These particles do not share the properties of the material they make up. There is nothing in the space between the particles that make up matter. The particles which make up matter are in constant motion in all physical states.
What is the science of atoms and molecules called?
The main field of science that studies atoms and molecules is called chemistry.
What does chemistry mean in love?
Simply put, the feeling of chemistry with another person is that of connection. It’s a draw to someone else that makes you want more of them. That doesn’t have to be in a romantic relationship context, though that is the way we most often use the word. A few common types of chemistry are outlined below.
What is molecule Byjus?
A group of two or more than two atoms of the same or different elements that are chemically bonded together is called a molecule. For example, two atoms of hydrogen and one atom of oxygen react with each other and form one molecule of water.
What is the most important molecule?
Deoxyribonucleic acid, or DNA. It’s probably your body’s most famous molecule, and rightfully so. It’s the one that tells yourselves what proteins to make, as well as how and where.
When or more molecules interact and molecules change?
Reactions occur when two or more molecules interact and the molecules change. Bonds between atoms are broken and created to form new molecules.
What makes iron rust and our blood turn red?
What makes iron rust and our blood red? Combined gasoline and oxygen in small controlled explosions.
Are minerals molecules?
The atoms in a mineral are arranged in an organised ‘atomic structure’. They connect together to form molecules, and the molecules stack together in a regular pattern to form a crystal. The shape of a crystal depends on the way the molecules are stacked up inside it.
