Why Does Sulphur Have a Valency of 4? Understanding Sulphur's Electron Configuration

Learn why sulphur exhibits a valency of 4 based on its electron configuration and bonding behavior in chemical compounds.

41 views

Sulphur has a valency of 4 due to its electron configuration. It has six electrons in its outer shell (3s2 3p4). For forming compounds, sulphur can share these six valence electrons with other atoms to achieve a stable octet configuration. In some cases, it forms four bonds by sharing electrons, giving it a valency of 4. This allows sulphur to participate in a variety of chemical reactions and compounds formation.
