Hope its helpful for you.

if it is correct then please mark me as brainliest

Answer 2

1. Monoatomic molecule:

The only chemical elements which are stable single atom molecules at standard temperature and pressure  are the noble gases. they exist as monoatomic molecule.examples are He,Ne,Ar etc.

2. Diatomic molecule:

​Diatomic molecules are molecules composed of only two atoms, of either the same or different chemical elements. The prefix di- is of Greek origin, meaning "two". If a diatomic molecule consists of two atoms of the same element, such as hydrogen (H2) or oxygen(O2), then it is said to be homo nuclear.
