Question

Give an example for monoatomic and polyatomic molecule.​

Answer 1

Answer:

Monoatomic-composed of 1 atom e.g. He, Ne, Ar (all noble gases are monoatomic) Diatomic-composed of 2 atoms e.g. H2 , N2 , O. Triatomic-composed of 3 atoms e.g. O. Polyatomic-composed of 3 or more atoms e.g. P4 , S.

Answer 2

• Answer:
• The noble gases (He, Ne, Ar, Kr, Xe, and Rn) are all monoatomic, whereas most other gases are at least diatomic.
• polyatomic molecules, e.g., carbon dioxide (CO2) and water (H2O).
