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.

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 ...

In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of 10 protons and 10 electrons, so the water molecule is neutral. The electron cloud model ...

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 ...
