If you mean "where are the valence electrons" then they are flying around the outside of the atom.
If you mean "why" then I don't know. they're just there to be the outermost set of electrons.
valence electrons are the electrons located in the outer shell of an atom which are available for reaction
In any atom, the valence electrons are located in the outermost shell. Chlorine has 7 valence electrons.

Valence electrons.
Valence electrons are located in the outermost shell in an atom. Chromium has only one valence electron.
There are 5 valence electrons present in the atom Nb (niobium), as it is located in group 5 of the periodic table.
The electrons that participate in chemical bonds are located in the "valence shell" or outer energy level of that atom. They are known as the valence electrons, and they are the only part of the atom that participates in a chemical reaction.
The total number of valence electrons in Boron's ground state is 2
nitrogen has 5 valence electrons. carbon has 4 valence electrons.
located in the outermost energy levels.
Valence electrons are the outermost electrons in an atom. They are located in the outer energy levels or orbitals, specifically in the highest principal energy level. These valence electrons are involved in chemical bonding and determining the atom's reactivity.
There are 2 valence electrons in an atom of magnesium. There are 5 valence electrons that are in an atom of phosphorus. There are 4 valence electrons that are in a silicon atom.
