Explanation:

Monoatomic Molecules

• Monatomic chemical elements contain only one atom.
• Monatomic chemical species can be ions or inert gases.
• Monatomic molecules are very stable; therefore, chemically inactive.
• Generally, monatomic molecules and ions are spherical in their geometry.

• Examples of monatomic molecules are noble gases. They are Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Ra).

Polyatomic Molecules

• Polyatomic chemical compounds have two or more atoms.
• Some polyatomic species are ions and some are molecules.
• Polyatomic molecules are electrically neutral.
• The geometry of the polyatomic chemical species varies depending on the number of molecules and the lone pairs present in the molecule.
• Examples of polyatomic molecules are KCl, KBrO3, C6H5COOH.
