Matter is not created nor destroyed in chemical reactions, the total mass and number of atoms before the reaction equals the total number of atoms and mass after the reaction. Conservation of mass law.

Two molecules of ammonia contain 6 hydrogen atoms.
diamonds are made of carbon atoms. enough said.
You think probable to diatomic molecules but these are not formed by a reaction.

it can react with up to four other atoms to form covalent bonds(:
Two molecules of ammonia contain 6 hydrogen atoms.
The coefficients in front of the reactants and products tell you how many atoms or molecules take part in a reaction. For example, the chemical equation 2 H2 plus O2 produces 2 H2O means that two hydrogen atoms react with one oxygen atom to produce two water molecules.

The CFC's molecules are ODS. They react with ozone to deplete it. The Chlorine and Fluorine are main atoms.
Neon is an element, so it is composed of atoms. Neon is also a noble gas, which means it generally does not react to form molecules of any kind.
The electrons, or the electron cloud, of an atom affect how it reacts chemically with other atoms and molecules.
