Question

why second ie of group 1 elements are greater than second ie of group 2 elements
​

Answer 1

Answer:

Second ionization energy of group 1 elements is higher than group 2 elements. When an electron is removed from the alkali metals, they form monovalent cations which have very stable configurations( same as that of noble gases). ... Thus, the secondelectron can be removed easily as compared to alkali metals
