Question

Which has more electron gain enthalpy among oxygen or sulphur?

Answer 1

sulphur is your answer it has more electron gain enthalpy

hope it helps you

Answer 2

The Oxygen has atomic number 8 and electronic configuration 2,6 and valency 2. The sulphur has atomic number 16 and electronic configuration 2,8,6 and valency 2. Both have same valency and same number of electron gaining capacity to complete their shell. So both have equal capacity of gaining electrons.
