what no. of SO4 u want to Now
SO4 contains the elements sulfur (S—1 atom) and oxygen (O—4 atoms)
atomic no. of S - 16 and O - 8
The no. of electron in SO4 = 16×1 + 8 × 4 = 48
or for Oxidation number
As you know the valency of oxygen is 2 : outermost orbit contains 6 electrons so valency = 6-8= -2
in SO4 -2 it has 2 negative charge so:
lets suppose O.N of S be x,
x + 4*(-2) = -2
x = -2 + 8
x= +6
