Why does it take Halley's comet so many years to resurface?

The electron cloud model is what the modern model is called. The fuzzy cloud around the nucleus resembles the ones shown in the Figure below for a helium atom. The electrons have the best chance of being in the densest area of the cloud.

Subsequently, why do comets not burn out?

Comets do not melt in the strict sense of becoming liquid. However, since they are composed partly of ice and other volatile compounds, they vaporize (turn directly to gas) when warmed in the vacuum of space by passing near the sun. It is this escaping gas that forms the comet's luminous tail.
