Hi all
yodaisneverwrong is talking about black holes evaporating via the hawking mechanism (hawking radiation). Briefly, black holes have non-zero temperatures, meaning they radiate. Hawking calculated that the radiation conforms to a blackbody spectrum. yodaisneverwrong is also correct in his surmise that the smaller a black hole gets the faster it radiates, the radiation rate is inversely proportional to mass.
A quick back of the envelope calculation shows that a proton (mass 1.67*10^-27kg) would have a schwarzschild radius of about 10^-54m, about a billion billion times smaller than the Planck length. It's unlikely you could compress a proton mass inside this distance.
More generally, when a black hole finally succumbs to runaway hawking radiation, it has effectively radiated away all of its mass, so nothing is left except what was radiated.
Hope this helps!

Yoda is way, way off on this one. Accepted theory states that a black hole is one possible outcome for a massively heavy star, which has exhausted its fuel, swelled, and begins collapsing. The core becomes so dense, that it pulls ever harder on the surrounding material, including passing light, draws it into it's core, which may be golf-ball sized, and expels it at great speed on the other side. This is all agreed theory, supported by a small amount of empirical evidence, but such Big astronomy is a learning process in itself, with few absolutes.

what. your whole idea of blackholes are wrong. the simplest answer is that blackholes are ultra heavy dead stars that have died out and collapsed into themselves. nothing evaporates.

the mass at the center of a black hole does not evaporate it collapses and as far as what it becomes, it would be a singularity if that's the answer you're looking for

"blackhole, it will evaporate almost instantly "
premise is incorrect.
