Answer 2

$\bold{\huge{\underline{Answer-}}}$

$\bold{\underline{Atom-}}$

An atom is the smallest unit of any element that can not remain in an independent state. It can easily participate in any chemical reaction, atom is inseparable i.e. it can not be divided

$\bold{\underline{Molecules-}}$

It can remain in this state, it is made up of any atomic molecule, they do not participate in the chemical reaction because these atoms are formed together so they can be divided, it is made up of kosos.
