Define Existence of atoms.

1.	Define Existence of atoms.
Answer» Atoms of most of the elements exist in the form of molecule or ion, since they are most reactive. For example, hydrogen, oxygen, chlorine, etc. However, atoms of some elements, which are non-reactive, exist in free-state in nature. For example helium, neon, argon, etc. Usually atoms are exist in following two forms - • In the form of molecules • In the form of ions
