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 ...

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 water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds ... Opposite polar ends of molecules attract and hold one molecule to another. Alcohol has one O–H bond which is ...
