# Why polar aprotic solvents don't surround negatively charged nucleophiles?

Protic solvents can form a tight shell around a nucleophile. But what's stopping any polar solvent from doing so? Shouldn't a polar solvent surround negatively charged $$\ce{F-}$$ with its partially positive side?

It looks like elements that end up partially positive (except for $$\ce{H}$$) are those that can have 3+ bonds ($$\ce{C}$$, $$\ce{S}$$), so they are mostly surrounded by other atoms. It's only $$\ce{H}$$ who has 1 bond and therefore ends up at the surface of the molecule and can interact with negatively charged nucleophiles.
