Answer:

Atoms : Atoms are the basic units of matter and the defining structure of elements. The term "atom" comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided.

Ions : An ion is a positively or negatively charged atom or group or atom. For Ex:Sodium ion,Magnesium ion,magnesium ion,chloride ion,oxide ion etc.
