Atoms, etc.

Pharmdeb asks:

What is the difference between atoms, molecules, and compounds?

etutor answers:

Atoms are the smallest chemical unit (although they are themselves made of smaller particles). Atoms (either the same or different ones) can combine together to form molecules. Compounds consist of molecules that contain two or more different atoms (e.g. O2 is oxygen - an element, because the tow atoms in it are the same; NaCl is a compound because it contains two different atoms).
