Solution

## Valence electrons:The electrons which are distributed in the outermost shell of the atom are called valence electrons.Valence electrons in a Sulfur atom:The element Sulfur$\left(\mathrm{S}\right)$ is in the third period and belongs to the Oxygen family (group 16). The atomic number of Sulfur$\left(\mathrm{S}\right)$ is 16.The electronic configuration of Sulfur$\left(\mathrm{S}\right)$ can be written as $1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^{4}$The valence electrons are the sum of the electrons in the outermost shell, that is two $3\mathrm{s}$ electrons and four $3\mathrm{p}$ electrons which gives a total of six valence electrons.Therefore, the valence electron in a Sulfur$\left(\mathrm{S}\right)$ atom is 6.
