What is the word for the definition of an electron in the highest occupied energy level of an atom

The word for the definition of an electron in the highest occupied energy level of an atom is " valence electron".

Explanation:

A valence electron is an external shell electron associated with an atom in chemistry and physics that can participate in the creation of a chemical bond if the highest occupied energy level of an atom is not closed. All atoms in a single covalent bond add one valence electron to form a mutual pair.

The periodic table showcases the arrangement of valence electrons group and block wise like:

Alkali metals have n s 1 as external shell configuration like H, Li, Na, K etc.Alkaline metals have n s 2 as external hell configuration like Be, Mg, Ca etc.p-block comprises group 13 to 18 having general electronic configuration n s 2, n p 1–6.d-block or transition metals have general electronic configuration (n-1) d 1–10, n s 1–2.f-block or inner transition metals have general electronic configuration (n-2) f^1–14 (n-1) d^0-1 n s^2.
