Answer 1

Answer: More than one atom of the same type chemically joined together

Step-by-step explanation:

An atom is the smallest unit of any matter which may or may not have independent existence. Example: Argon (Ar) is an element which exist as Ar atom only.

Molecule is the smallest unit of any matter which always have independent existence. For example: Hydrogen (H) is an element which can exist in nature as
`H_2` molecule only.

Atoms of different elements chemically joined together is called as a compound. Example:
`H_2O` is a compound formed by chemical combination of hydrogen (H) and oxygen (O) atom.
