Why do we use other bonding theories in addition to the lewis model?

Full Question:

Why do we use other bonding theories in addition to the lewis model?

a) Lewis model is not suitable for all molecules or ions. b) Lewis model cannot predict all of the properties of a molecule or ion. c) Lewis model is too complicated.

b) Lewis model cannot predict all of the properties of a molecule or ion.

Explanation:

Lewis structures, also called electron-dot structures or electron-dot diagrams, are diagrams that show the bonding between atoms of a molecule, and the lone pairs of electrons that may exist in the molecule.

Lweis  model does not explain the geometry of molecules, how the bonds form, or how the electrons are shared between the atoms hence the need to use other bonding theories.
