hey user here is ur ans is......


Atom- An atom is the smallest unit of elements that can't exist freely (except for noble gas) and that shows all the properties of that element.

For example- H is an atom of Hydrogen element.

Similarly He,N,O,F,Cl etc.

Molecule- A molecule is the smallest unit of elements and compounds that can exist freely and that shows all the properties of that element or compound.

There are two kinds of molecules-

Molecule of element- The smallest unit of elements that can exist freely and that show all the properties of that element are called molecule of element. For example- O2,O3, H2 , N2 etc

Molecule of compound- The smallest unit of compound that can exist freely and show all the properties of that compound is called molecule of compound.For example- H2O, CO2, HNO3,H2S and many more.

All pure substances are either elements or compounds and the smallest unit of all pure substances showing their properties are either atoms or molecules.

That is all I have.

hope it's help!!
