How many of the 6 valence electrons in sulfur are used in covalent bonding in sulfur tetrachloride and dislufur diflouride?

Answer 1

4 for sulfur tetrachloride and 2 for disulfur difluoride

Answer 2

In sulfur tetrachloride (SCl4), all 6 valence electrons of sulfur are used, as sulfur forms 4 covalent bonds with 4 chlorine atoms. In disulfur difluoride (S2F2), 4 of the 6 valence electrons of sulfur are used, as sulfur forms 2 covalent bonds with another sulfur atom and 2 covalent bonds with 2 fluorine atoms.
