How do you write the second ionization energy equation?
It is the energy needed to remove a second electron from each ion in 1 mole of gaseous 1+ ions to give gaseous 2+ ions….More ionisation energies.
| Al(g) Al+(g) + e- | 1st I.E. = 577 kJ mol-1 |
|---|---|
| Al+(g) Al2+(g) + e- | 2nd I.E. = 1820 kJ mol-1 |
| Al2+(g) Al3+(g) + e- | 3rd I.E. = 2740 kJ mol-1 |

What is second ionization energy?
An element’s second ionization energy is the energy required to remove the outermost, or least bound, electron from a 1+ ion of the element. Because positive charge binds electrons more strongly, the second ionization energy of an element is always higher than the first.
