Ionization energy of an element is:

Ionization energy of an element depends on :

Why the second lonization energy is more than the first ionization energy for any element ?

The first four ionization energies of an element are 191, 578, 872 , and 5962 "kca"l . The number of valence electrons in the element is.

The first five ionization energies of an element are 801,2428,3660,25030,32835 "in" "kJ"//"mol" . Then the element could be.

The first four ionization energies of an element are 191, 578, 872 , and 5962 "kcal . The number of valence electrons in the element is.
