A black hole forms as an aging star abruptly collapses when it ceases nuclear fusion. This occurs after the star has consumed its component elements in this order: hydrogen, helium, carbon, and then heavier elements such as neon, oxygen, and silicon, leading up to iron. Once the core is primarily iron, fusion no longer generates energy, resulting in a gravitational collapse when the star's internal pressure can no longer support its mass.
