In a molecule of sulphur tetrafluoride (), how many lone pairs of electrons remain localized strictl — p Block Elements Chemistry Question

💡 Solution & Explanation

Sulphur has 6 valence electrons. In $SF_4$, it forms four single bonds with four fluorine atoms using 4 electrons. The remaining 2 electrons constitute exactly 1 lone pair, resulting in $sp^3d$ hybridization and a see-saw geometry.
