Depends on the bomb: Uranium, Plutonium, Lithium, and Hydrogen are the most common. Different bombs use different ones or different mixtures.
Uranium, typically enriched to ~3% Uranium-235.
Uranium-235 or Plutonium-239, or Uranium-233. Also many transuranics, like Americium make good fuel.
The main character in creating the nuclear bomb was Robert Oppenheimer.
Uranium is the main fuel used, but in some countries a mixture of uranium and plutonium is also used (MOX fuel)
Fission fuels: (heavy elements)Plutonium-239Uranium-235Uranium-233Fusion fuels: (light elements)Lithium deuterideTritiumDeuteriumFew modern bombs depend on only one of these fuels. The majority use at least one fission fuel and one fusion fuel, to raise the efficiency of usage of each.
The main purpose of the hydrogen bomb was to create a much more powerful and destructive nuclear weapon than the atomic bomb. It was designed to release energy from nuclear fusion reactions, which is many times greater than that of nuclear fission reactions used in atomic bombs.
That is the main use, to fuel nuclear power plants

Uranium
The main element used in fuel cells is typically hydrogen, which is combined with oxygen to produce electricity through an electrochemical reaction.
The main fuel for nuclear reactions in stars is hydrogen. Through a process called nuclear fusion, hydrogen atoms combine to form helium, releasing energy in the form of light and heat. This process powers the stars and allows them to shine brightly.
Yes, fluoride is sometimes used in the production of nuclear weapons to help purify and enrich uranium for fuel or bombs. However, the amount of fluoride present in an atomic bomb itself is typically very small and not a primary component of the weapon.
