How Does Sulfur Exhibit Variable Valency and What Are Its Common Oxidation States?

Learn how sulfur shows variable valency by promoting electrons to 3d orbitals, resulting in oxidation states +2, +4, and +6.

31 views

Sulfur exhibits variable valency due to its ability to promote electrons to higher energy levels. In its ground state, sulfur has six valence electrons: two in the 3s orbital and four in the 3p orbitals. By promoting one or more electrons to the empty 3d orbitals, sulfur can exhibit valencies of +2, +4, and +6. This flexibility allows sulfur to form a variety of compounds with different chemical properties.
