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) →
When an electron absorbs energy, it will move up from a lower energy level to a higher energy level, called the "excited state" of the negatively-charged subatomic particle.<span> However, the absorbed energy is released within a small interval of time and the electron moves down to its "ground state."</span>
The atomic number is always equal to the number of protons. It will be equal to the number of elections also if the atom has a neutral charge.

The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Halogens are highly reactive because they readily gain an electron to fill their outermost shell
