Answer:

In the valence electron shells.

Explanation:

The valence electrons are the electrons of an atom that are located at the uppermost shell of the electron, which is called the valence shell.

For example, look at this picture of a fluorine atom:

It has #7# electrons in its second shell, which is its outermost shell, and so it will have #7# valence electrons.

These electrons are mainly responsible for an element's reactivity.
