Question

What is the difference between an atom and a molecule?

Answer 1

Answer:

Molecules are made of atoms.

Answer 2

Answer:

Hope this helps!

Explanation:

An atom is the smallest part of an element that maintains the identity of that element.

A molecule is the smallest part of a compund that maintains the identity of that compound. So examples of a molecule are diatomic elements like $O_{2} , N_{2}$

A Bonus Tip: I dont want to confuse you but something I learn that benifited me is to know that molecules are not compounds. For a substance to be considered a compound it has to be more than one atom. In the past, I would confuse molecules as compounds because it would be O$_{2}$ but its still the same atom so its a molecule not a compound!
