The final elements fused in a star of the mass of our Sun are Oxygen then Carbon. Therefore a white dwarf core could be regarded as a solid, gigantic diamond.
from silicon to iron, about a day.
It depends on how massive the star is and what part of its life its at. Most of the time the core is the hottest, but after a star runs out of its current fuel it will start fusing elements in a shell around its core out to the surface or photosphere. While these shells are burning they are the temporary hotspots of the star, while the core gets hotter and hotter.

The core contracts and becomes a black hole.

Assuming I've understood the question, it would be nickel. Nickel is the end product of the silicon burning process, since going any further (the next step up would be zinc) is endergonic.
an expanding Shell of hydrogen gas envelop the core of the star which collapses ,it becomes a red giant. In more massive star with hotter core ,helium fuses to carbon,silicon or oxygen, synthesizing the heavier element .even more massive stars may burns iron generating a cooling effect . The core implodls and the outer layer of the stars are bloom away as a supernova
Star.
Hydrogen into Helium.
Yes, if the star is massive enough when the core collapses a supernova explosion happens.
from silicon to iron, about a day.
Neutron Star
yes, it sure is. (if the core is massive enough.) if not, it becomes a Neutron Star.
For a star like ours, the black dwarf stage For an immensely massive star, a back hole.

A neutron star is what is left of the core of a massive star after it dies. The core collapses under the force of gravity, crushing itself from a size far larger than Earth to about the size of a city but still with a mass up to 3 times that of the sun. If it is any more massive it becomes a black hole.
