Solution

$A t o m i c n u m b e r o f S = 16 = 16 e l e c t r o n s$
$A t o m i c n u m b e r o f o x y g e n = 8 = 8 e l e c t r o n s$
$I n s u l f a t e i o n, t h e r e i s o n e s u l f u r a t o m s a n d 4 o x y g e n a t o m s .$
$- 2 c h a r g e s h o w s t h a t t h e r e a r e 2 e x t r a e l e c t r o n s i n t h e i o n .$

$S o t o t a l n u m b e r o f e l e c t r o n s i n t h e S O_{4}^{2 -} = 16 + 4 \times 8 + 2$
$= 50 e l e c t r o n s$
