Why sulphur has positive or negative in resonating structure?

As I mentioned before, the resonance form(s) of lowest energy are those where the charges are minimized. However, sometimes you can’t get around it: you have to put a charge somewhere. Last time I talked about the principles involved in deciding where best to put a negative charge: on the least basic atom. Today I’ll talk about the opposite situation: where to put a positive charge.
There are really one main principle to think about when deciding which site will stabilize positive charge the best. Recall the one sentence summary of chemistry: opposite charges attract, like charges repel. Electron-poor atoms are stabilized by adjacent electron-rich atoms. Electron poor atoms are destabilized by electron-poor atoms.
