Question

Select the incorrect statement based on Neils Bohr’s connection between the periodic
table and quantum theory.

A) Elements in the same group such as Na and Rb both have 1 valence electron, but
differ in the number of core electrons.

B) Because elements in the same group have similar electron configurations, both I
and F will have 7 electrons in their outer most p orbitals.

C) Because elements in the same group have the same number of electrons in the
outer shell, both N and P have 5 valence electrons.

D) Because elements in the same group have the same principle quantum number, both Zn and Cd have n = 3 values.

The Incorrect statement is D)

Zinc (Zn) and Cadmium (Cd) are belongs to same group and different periods and their principal quantum numbers are different.
