Identify one disadvantage to each of the following models of electron configuration: dot structures arrow and line diagrams written electron configurations

The disadvantages or the limitations are as follows:

Dot structures: based on an empirical trend “atoms like octets”, not a rigorous description of the true nature of electrons

Arrow and line diagrams: Does not say much of the possible properties of the molecule.

Written electron configurations: no 3D representation of the molecule or the atom
