The number of electrons present in the valence shell of $S$ in $SF_6$ is $12$.

Vedclass · Answer

(A) In $SF_6$,the sulfur atom forms $6$ covalent bonds with $6$ fluorine atoms,resulting in $12$ electrons in its valence shell (expanded octet).Ionic reactions are generally very fast due to the presence of ions in solution.According to $VSEPR$ theory,$SnCl_2$ has a lone pair on the central atom,making it a bent (angular) molecule,not linear.The stability of ionic compounds depends on the lattice energy,which increases with the charge density of the cation. Thus,the order of stability is $Al^{3+} > Mg^{2+} > Na^+$. However,the statement in option $A$ is a direct fact regarding the expanded octet of $S$ in $SF_6$.
