The second ionization energy of K is maximum, because the second electron is removed from fully filled 3p? subshell. The second ionization energies of group 2 elements decrease down the group.
Hence, second I.E. of Ca > second I.E. of Ba.

Due to the larger size of the Cl-atom, the addition of an electron in the outermost orbit produces less electronic repulsion with respect to the F-atom. The following are the electron gain enthalpies in (KJ) of halogens:
F → -328, Cl → -349, Br → -325, I → -295
