The most massive (and luminous) star known to date is the Wolf-Rayet star R136a1, which is estimated at 265 times the mass of our Sun. It is located in the Tarantula Nebula in the Large Magellanic Cloud. (Note that it is not the largest known star).

Iron is the heaviest element that a star can produce through fusion before going supernova. This is because iron requires more energy to fuse than it can produce, leading to the collapse of the star.
Iron is the heaviest element that can be produced by normal processes inside a star through nuclear fusion. Elements heavier than iron are typically formed in supernova explosions or through other stellar processes.
The final core element for a massive star is iron. When a massive star exhausts its nuclear fuel, iron builds up in its core due to fusion reactions. Iron cannot undergo further fusion to release energy, leading to a collapse and subsequent supernova explosion.
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.
The most common element in a young star is hydrogen. During the star formation process, vast amounts of hydrogen gas collapse under gravity to form a new star. This hydrogen fuel is what powers nuclear fusion reactions in the star's core, creating energy and sustaining the star's brightness.
