Actually, those are all elements (Period Teble of Elements), and not all elements are atoms, elements also describe molecules with more than one atom as long as the atoms are all the same element. For instance, O2 is still oxygen, as well as ozone (O3). Also, none of the elemental dragon elements are actual elements, although they were once thought to be in ancient times. To Vortex_Master, water is a compound (H2O), but fire isn't. It's just the rapid oxidation of a material through combustion.
All that with no Google. You're welcome.
As for Radly, join the WolfPack, where the members know what they're talking about.
