There are 50 electrons in a sulphate ion.
16 in the sulfur base 8 in each of the 4 oxygen and 2 for the negative charge
this equals 50
There are 32 valence electrons in the Lewis structure of the hydrogen sulfate ion.
It has 4.
three
There are 5 sigma bonds along with 2 pi bonds in oxalate ion and 2 ionic bonds with potassium.
2 or more
This formula is itself an ion with -2 charge. It has 2 carbon atoms and 4 oxygen atoms per ion. An oxalate ion has six atoms.
Resonance effect: It is a way of describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by one single Lewis formula.A molecule or ion with such delocalized electrons is represented by several contributing structures called as resonance structures or canonical forms. Inductive Effect: It is a permanent effect. When group attached to carbon atom attract electrons from them or push the electrons toward it is called as Inductive effect.
The sulfate ion has four resonance structures.

There are three possible, equally distributed, resonance structures of nitrate (NO3-).Cf. Related links for the possible Lewis structure of them, on the lowest half of that page.
There are two resonance structures for bromate - two of the oxygens are double bonded to bromine, and one is single bonded. The double bonded bromines share the electrons between all three, creating two equivalent resonance structures.
