The Bohr model

Students often get confused between Rutherford’s model and Bohr model of an atom. They interpret the postulates of both these models to be the same, which is incorrect. Rutherford’s model differs from Bohr’s model in the following ways:

Binding Energy (MJ/mol)
(A) Removing 3 electrons releases more energy than removing 2 electrons.
(B) Scandium is in Group 3, and atoms only lose the number of electrons that will result in a
noble
gas electron configuration.

(C) The amount of energy required to remove an electron from the 3d sublevel is close to that for
the 4s sublevel, but significantly more Energy is needed to remove electrons from the 3p
sublevel.
(D) Removing 2 electrons alleviates the spin-pairing repulsions in the 4s sublevel, so it is not as
energetically favorable as emptying the sublevel completely.
