Question

Which of the following has highest electron gain enthalpy?
(A) $\left[Ne\right]3s^{2}3p^3$
(B) $\left[Ne\right]3s^{2}3p^4$
(C) $\left[Ne\right]3s^{2}3p^5$
(D) $\left[Ne\right]3s^{2}3p^2$

• A. (A)
• B. (B)
• C. (C)
• D. (D)

Answer 1

The correct option is C (C)

The element $\left(C\right)$ will have highest electron gain enthalpy as it easily gains one more electron to achieve stable configuration of next inert gas.
