Aluminium Ionization Energy

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