While making the lewis structure of NO3- we make it normally but while making the lewis structure for H2SO4 we consider the formal charge of the sulphur the central atom to be zero then the structure is completed.. Why like this? in the lewis structure of NO3- is not zero still the structure is correct but in H2SO4 after putting all the electrons correctly then we check the formal charge to be zero then only our structure is completed.. why?
