(B) To determine if an ion is non-polar,we must check if its net dipole moment is zero.$1$. $XeF_5^-$: It has a pentagonal planar geometry with a lone pair,resulting in a non-zero dipole moment (polar).$2$. $SO_3^{2-}$: It has a trigonal pyramidal geometry,resulting in a non-zero dipole moment (polar).$3$. $SO_4^{2-}$: It has a tetrahedral geometry $(T_d)$,which is highly symmetrical,so the net dipole moment is $0$ (non-polar).$4$. $ClO_4^-$: It has a tetrahedral geometry $(T_d)$,which is highly symmetrical,so the net dipole moment is $0$ (non-polar).$5$. $PO_4^{3-}$: It has a tetrahedral geometry $(T_d)$,which is highly symmetrical,so the net dipole moment is $0$ (non-polar).$6$. $NO_2^+$: It has a linear geometry ($sp$ hybridization),so the net dipole moment is $0$ (non-polar).Therefore,the non-polar ions are $SO_4^{2-}, ClO_4^-, PO_4^{3-},$ and $NO_2^+$. There are $4$ such ions.

How many ions are non-polar ions?
$XeF_5^-, SO_3^{2-}, SO_4^{2-}, ClO_4^-, PO_4^{3-}, NO_2^+$
