Answer
a) The first ionization energy is the energy that 1 mole of an atom in a gaseous state requires in order to abandon the electron that is least bound.
b) The second ionization energy is the energy that 1 mole of an 1+ ion of the element in a gaseous state requires in order to abandon the electron that is least bound.
