Valence electrons are electrons that are in the outermost orbitals of an atom. In the periodic table the elements are divided into groups. All elements of the first main group have one valence electron. All elements of the second main group have two valence electrons. And so on:

group 1 - 1 valence electron
group 2 - 2 valence electrons
group 13- 3 valence electrons
group 14 - 4 valence electrons
group 15 - 5 valence electrons
group 16 - 6 valence electrons
group 17 - 7 valence electrons
group 18 - 8 valence electrons
