Lewis acids are molecules in which the core atom has more than 8 valence shell electrons and hence can act as electron acceptors.

Explanation:

Lewis Acids, Electrons can be accepted by an atom, ion, or molecule with an incomplete octet of electrons. Boron trifluoride and aluminium fluoride are two examples

The hardness and softness of lewis acid are used to classify it. Small, nonpolarizable atoms are referred to as "hard," while bigger, more polarizable atoms are referred to as "soft."

Hard acids include H+, alkali/alkaline earth metal cations, boranes, and Zn2+, to name a few.

Ag+, Mo,  are soft acids
