Chromium Ionization Energy






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


Ionization Energy

Cr -> Cr1+ = 652.7 kJ/mol = 156.15 Kcal/mol
Cr1+ -> Cr2+ = 1592 kJ/mol = 380.86 Kcal/mol
Cr2+ -> Cr3+ = 2987 kJ/mol = 714.59 Kcal/mol
Cr3+ -> Cr4+ = 4740 kJ/mol = 1133.97 Kcal/mol
Cr4+ -> Cr5+ = 6690 kJ/mol = 1600.48 Kcal/mol
Cr5+ -> Cr6+ = 8738 kJ/mol = 2090.43 Kcal/mol
Cr6+ -> Cr7+ = 15550 kJ/mol = 3720.10 Kcal/mol
Cr7+ -> Cr8+ = 17830 kJ/mol = 4265.55 Kcal/mol
Cr8+ -> Cr9+ = 20220 kJ/mol = 4837.32 Kcal/mol
Cr9+ -> Cr10+ = 23580 kJ/mol = 5641.15 Kcal/mol
