Examples include O2, CO, NO etc.

A triatomic molecule is a molecule which consists of three atoms. Examples include CO2, NO2, H2O etc.

Answer 2

Diatomic-$O_2, HCl$.

Triatomic- $H_2O$.

• The molecules or compounds that contain two atoms are called diatomic.
• For example, $O_2, HCl$ are diatomic as oxygen gas contains two Oxygen atoms and HCl contains one Hydrogen and one chlorine atom.
• The molecules or compounds that contain three atoms are called triatomic.
• For example, $H_2O$ is triatomic as water contains one oxygen atom and two hydrogen atoms.
