Francium Ionization Energy






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


Ionization Energy

Fr -> Fr1+ = 400 kJ/mol = 95.69 Kcal/mol
Fr1+ -> Fr2+ = 2100 kJ/mol = 502.39 Kcal/mol
Fr2+ -> Fr3+ = 3100 kJ/mol = 741.63 Kcal/mol
Fr3+ -> Fr4+ = 4100 kJ/mol = 980.86 Kcal/mol
Fr4+ -> Fr5+ = 5700 kJ/mol = 1363.64 Kcal/mol
Fr5+ -> Fr6+ = 6900 kJ/mol = 1650.72 Kcal/mol
Fr6+ -> Fr7+ = 8100 kJ/mol = 1937.80 Kcal/mol
Fr7+ -> Fr8+ = 12300 kJ/mol = 2942.58 Kcal/mol
Fr8+ -> Fr9+ = 12800 kJ/mol = 3062.20 Kcal/mol
Fr9+ -> Fr10+ = 29300 kJ/mol = 7009.57 Kcal/mol
