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
Lewis structures do not tell you anything about molecular geometry you have to invoke hybridisation argumments or us VSEPR (AXE theory) to make predictions
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.
Rather hard to represent 3-d depictions of molecular structures on a 2-d surface short of folding the paper. That's around all otherwise it is a simple and common way to depict chemical structures Lewis dot Structures and Covalent bonds are completely different. The Lewis dot takes or gives, while covalent bonds share.
Resonance structures refer to bonding in molecules or ions that cannot be correctly represented by a single Lewis structure. The Lewis dot structures show valence electrons.
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.
Sulfur dioxide has three resonance structures. A singly bonded oxygen would have 3 unshared electron pairs while a doubly bonded oxygen would have 2. The sulfur has one pair.
In chemistry, resonance is a way of describing bonding in certain molecules or ions by the combination of several contributing structures (or forms, also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory
resonance forms are individual lewis structure in cases where two or more lewis structure are equally good descriptions of a single molecule .
Because some covalent compounds have more then one valid Lewis dot structure
Resonance structure
Resonance
Yes
when it can be shown with two or more Lewis structures. :P

yes
