Write equations that show the processes that describe the first, second, and third ionization energies for a gaseous gadolinium atom. Express your answers as chemical equations separated by commas. Identify all of the phases in your 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) →  

they are both synthetic elements
