Question

Which one of the following statements about atomic structure and quantum

            numbers is incorrect?

A. The n = 4 main energy level has 4 types of orbitals.

B. The maximum number of electrons in a given d sublevel is 5.

            C. The value of m l cannot be 3 in the n = 3 main energy level.

            D. There are no d orbitals in the n = 2 main energy level.

            E.   In a particular atom, if one electron has the set of three quantum numbers n = 3, l = 2, m l = – 2, only one other electron in the atom can have these same three quantum numbers.

Please explain answer

Explanation / Answer
