Question

Give the difference of molecule of a element and molecule of a compound separately

Answer 1

Let's start with the definition of molecule. Shall we?

A molecule is the smallest particle of an element or a compound which can exist freely. For example:- Molecules of oxygen, nitrogen, Carbon dioxide etc can exist freely.

Now,

>>Molecule of an element is made up of same kind of atoms and thus are called homoatomic.

For example:-

He, Ne etc are monoatomic molecules

H2,N2,O2 are called diatomic.

>>Molecules of compounds are made up of atoms of more than one element and thus are known as heteroatomic.

molecules.

For example:-

HCl is diatomic

H2O, CO2 is triatomic.
