Pls answer Q127:
127. Among the following elements (whose electronic configuration is given below ) the one having the highest ionisation energy is.
(1) [Ne] 3s2 3p3 (2) [Ne] 3s2 3p4
(3) [Ne] 3s2 3p5 (4) [Ar] 3d10 4s24p2
Dear student
Option 1 is correct
Because here the last orbital is half filled and half filled orbitals are extra stable, thus having high ionisation energy.
