Zeff has to do with the electron shielding. The second ionization energy is that required to remove the next electron, and so on. Take, for example, an alkali metal atom. The second ionization energy of calcium is higher than its first ionization energy. There are four factors that affect the size of the first ionization energy: The charge on the nucleus. This is because there aren’t enough electrons to neutralize the positive charge of the nucleus. I -> I + + e - This process can be repeated many times, but the energy cost is increased dramatically. Sandeep Gurram 2E. The nth ionization energy refers to the amount of energy required to remove an electron from the species with a charge of (n-1). There is an ionization energy for each successive electron removed; the ionization energy associated with removal of the first (most loosely held) electron, however, is most commonly used. First And Second Ionization Energy. Ge -> Ge + + e - This process can be repeated many times, but the energy cost is increased dramatically. This is the first ionization energy: 1st ionization energyX → X+ + e-The energy needed to remove an electron from a cation to form a dication is called the second ionization energy and so fort. 7, 48610 kJ/mol.
