Why 2nd ionization energy is greater than 1st Ionization energy
Answers
Answer:
Question:
Why is second ionization energy greater than first?
Ionization Stages:
Atoms become ionized (charged) by removal of an electron from the outermost and, and possibly, inner shells. Removal of a second electron can occur from the same outermost shell (magnesium, for example), or from an inner shell (sodium, for example). The energy to remove one electron from a neutral atom is called the first ionization energy, and the energy required to remove the second electron is called the second ionization energy.
The best example for studing it is Hydogen.
