How many valence electrons are present in a Sulfur atom?

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 SulfurS is in the third period and belongs to the Oxygen family (group 16).
  • The atomic number of SulfurS is 16.
  • The electronic configuration of SulfurS can be written as 1s22s22p63s23p4
  • The valence electrons are the sum of the electrons in the outermost shell, that is two 3s electrons and four 3p electrons which gives a total of six valence electrons.

Therefore, the valence electron in a SulfurS atom is 6.
