Answer
Ionization energy is the amount of energy necessary to remove an electron from an atom when the element is in its gaseous state. The first ionization energy is the amount of energy required to remove an electron from a neutral atom. The second ionization energy is the amount of energy required to remove a second electron from a former neutral atom or, in other words, to remove an electron from a cation with charge 1+.
