Question

Which of the following has a positive value of electron gain enthalpy? (A) N (B) P (C) As (D) Sb

Tardigrade Admin · Accepted Answer

Electron gain enthalpy of nitrogen is +31 kJ / mol. Due to smaller size, there are inter electronic repulsions, and also extra stability due to exactly half filled configuration (2 p3), it is difficult for an electron to enter the shell.
