Answer:
Gd(g) →

Explanation:
Ionization energy is the energy required to remove an electron from a gaseous atom or ion.
The first ionization energy is the energy required to remove the valence electron(outermost) from a neutral atom:
Gd(g)→ 
The second ionization energy is the energy required to remove next/second electron from
ion. The second ionization energy is always higher than the first:
(g) → 
The third ionization energy is the energy required to remove third electron from
ion:
(g) →
