Atoms combine and bond to each other to make molecules. A molecule is made up of a certain number and type of atom. For example, water (H 2 O) is always made from two hydrogen atoms and one oxygen ...

The molecule has one shape when ferrying oxygen molecules and a slightly different shape when it is not Its 10,000 atoms are assembled into four chains, each a helix with several bends.

This particle diagram represents water or, to use its chemical formula, H₂O which is a compound of the elements hydrogen and oxygen. In one molecule of water, there are two hydrogen atoms and ...

In the reaction, the bonds in the methane and oxygen molecule come apart, the atoms rearrange and then re-bond to form water and carbon dioxide. The little number written at the lower right after an ...
