Question

Of and s which one has higher negative electron gain enthalpy

Answer 1

Sulphur has higher electron gain enthalpy because when an atom Mantis its outermost shell in oxygen its surface and mutual repulsion due to the electron cloud of the oxygen so the electron gain enthalpy decreases than sulphur

Answer 2

Answer:

S has high electron gain enthalpy because in sulphur there is more inter-electronic repulsion than oxygen, therefore, more energy is released in case of sulphur on gaining electrons.
