Solution Step1 Ionization energy is the energy required to remove the outermost, or highest energy, electron from a neutral atom in the gas phase. 2 1, For Al having electronic configuration [Ne]3s 3p it is the energy required to remove the outermost 3p electron.The equation can be written as + - Al(g)------------> Al (g) e ------> I 1 The second ionization energy is the amount of energy needed to remove the second outermost electron.For Al it is the energy required to remove the outermost 3s electron.The equation can be written as + 2+ - Al (g)-------------> Al (g)+ e -------> I 2 The third ionization energy is the amount of energy needed to remove the third outermost electron.The equation can be written as Al 2+ --------------> Al 3+ + e -------> I (g)- (g) 3
