Identify one disadvantage to each of the following models of electron configuration: Dot structures Arrow and line diagrams Written electron configurations

Dot structures do not show the distribution of electrons in orbitals and take up a lot of space.

Arrow and line diagrams take up a lot of space and make it difficult to count electrons.

Written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.

(re-write in your own words this is off engenuity)

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
