Question

out of florine and oxygen whose 2nd ionisation enthalpy is more and why​

Answer 1

Answer:

oxygen have more 2nd ionisation enthalpy than florine.

Explanation:

this is because oxygen has stable electronic configuration .After removing one electron O+ shows greater ionisation enthalpy than F+.

Answer 2

Answer:

Second I.P  of O>F

Explanation:

Because

after removing first electron from F

F it gets electronic conf same as O

after removing first electron from O

O gets e.c same as N

as N has half filled configuration which is more stable compared to O

thats why Second I.P  of O>F
