It is because it collapses after it has run out of "fuel".
Stars with a low to medium mass will become white dwarfs. Massive stars will become neutron stars or black holes.
the simple reson is mass.......that is if the star under consideration is a heavy one, it is more likely to turn into a black hole and if it is comparatively smaller it is prone to turn into a neutron star or a white dwarf
Sometimes if the conditions are just right a huge diamond! (the final stage of nucleosynthesis of stars that are not more massive is carbon Theoretically, they get dimmer and dimmer until they become "black dwarfs".
A nebula does not directly turn into a white dwarf. A nebula will collapse to form stars. Low to medium mass stars become white dwarfs after they die. Some are the result of a supernova and do not collapse, they merely dissipate over time. The Crab Nebula is the most prominent example of this.

they turn to white dwarfs then red giants and then they explode
Actually if a star is medium or low mass is will run out of fuel and turn into a red giant, once the stars atmosphere slowly drifts away and the core is remaining it will eventually become a white dwarf For more massive stars it will turn in to a super giant the will cause a supernova, after the supernova the star can either a black hole or a neutron star
Yes. The lowest mass stars are red dwarfs while many older stars turn into red giants and red supergiants.
There are small hot stars - White dwarfs, neutron stars but by furtue that they are hot, means they are not near the end of their lives. It takes a long long time for all the residual heat to escape into the Universe. So, there are NO hot stars near the end of it's life.
they live for a long time as regular sized stars then eventually they turn into red giants and explode then turning into a white dwarf
lead is an Element, so it's rather difficult to explain. A star burns by fusing hydrogen into helium and helium into lithium and so on right up the periodic table. Useually stars get to about iron before they turn into black dwarfs or white dwarfs but larger stars that burn hotter can create heavier elements like gold and lead.
It won't turn direclty into a black dwarf. Some stars will turn into a white dwarf; when the white dwarf cools down (it no longer produces energy), it will become a black dwarf. It is not likely that there are black dwarves yet, since the Universe isn't old enough; this is an expected future stage in the development of some stars. and be cause yolo
