the chemical properties of an atom are determined by the outermost electron shell.
Examples of electron shell

Electrons that constitute a dense electron shell surrounding the bubble move with relativistic speeds and thus have high inertia.

Monatomic ions are formed by the addition of electrons to the valence shell of the atom, which is the outer-most electron shell in an atom, or the losing of electrons from this shell.
From the en.wikipedia.org
The outermost electron shell of an atom in its uncombined state is known as the valence shell, and the electrons in that shell are called valence electrons.

In a rubidium atom, just one electron occupies the outer valence shell.
