# The definition of formal Charge

Ok, most people including me know that formal charge is just a book-keeping tool. I know how to calculate it, apply it to Lewis structures etc etc. But I am confused in its very basic definition which says - "Formal charge is the charge on an atom if the electronegativity differences are ignored" . If the electronegativity difference is ignored, then how can an atom have charge ? I know this is not a place to ask such a basic question , but still I am very confused about this miniscule definition.

Take a look at this previous question to see if it helps you out. –  Nicolau Saker Neto Jul 20 at 12:46
@NicolauSakerNeto Thanks but I know all that (how to calculate and use formal charges). I just want an explanation to this definition. –  Hardik Jul 20 at 13:07
