Question

Out of S and P which has more ionisation enthalpy value

Answer 1

I think it is Phosphorous even though it is in 15 grp before sulphur it has a half filled 3p orbital which makes it difficult to remove an electron while in sulphur there one paired electron so easier to remove as in oxygen and nitrogen. Thanku

Answer 2

p has more enthalpy value as it is in 15 group and thus loose 3 electrons.
