Boron Ionization Energy

The Boron Ionization Energy is the energy required to remove from atom one mole of electrons with subsequent production of positively charged ion of Boron.
B -> B⁺ + e^-
This process can be repeated many times, but the energy cost is increased dramatically. The general equation for the Boron is:
B^N+ -> B^(N+1)+ + e^-

B -> B¹⁺ = 800.6 kJ/mol = 191.53 Kcal/mol
B¹⁺ -> B²⁺ = 2427 kJ/mol = 580.62 Kcal/mol
B²⁺ -> B³⁺ = 3660 kJ/mol = 875.60 Kcal/mol
B³⁺ -> B⁴⁺ = 25025 kJ/mol = 5986.84 Kcal/mol
B⁴⁺ -> B⁵⁺ = 32822 kJ/mol = 7852.15 Kcal/mol
