Electron-dot notation shows only the electrons in the innermost/outermost energy shell of
an atom. These electrons are called valence/orbital electrons and are/ are not involved in
chemical reactions. Elements with a full outer energy shell are typically very reactive/
unreactive.

Outermost energy shell

Valence electrons

are involved

Unreactive

Explanation:

Electron-dot notation shows only the electrons in the outermost energy shell of  an atom. These electrons are called valence electrons and are involved in  chemical reactions. Elements with a full outer energy shell are typically very reactive.

The notation shows only the chemical symbol of the element surrounded by dots that represents the valence electrons. The chemical symbol denotes the nucleus and all electrons except the valence electrons. These valence electrons are the outer shell electrons. They take part in chemical reactions and determines the chemical properties of an atom. Elements with completely filled outer orbitals are unreactive and they are the noble gases.
