Maximum number of orbitals in

3^{\text {rd }}

excited state of

L i^{+2}=x

. Electronegativity (Pauling scale) of most electronegative element

=y

. Then find value of

\left(\frac{x}{y}\right)

View answer and explanation

Correct option: A

Option A (4) is correct because the maximum number of orbitals in the 3rd excited state is 16, and the electronegativity of Fluorine is 4.0, so 16/4 = 4.
