how much uranium is in a bomb?

According to the Union of Concerned Scientists, a nuclear bomb needs about 33 pounds (15 kilograms) of enriched uranium to be operational.

Basically you divide Avogadro constant by the atomic mass of the element to find the number of atoms of that element in one gram. So Uranium-235 contains 6.02214179×1023 / 235 = about 2.5626135×1021 atoms per gram.

The element uranium, BY DEFINITION, is the actinide element with 92 protons in its nucleus. Of course, the element could have different numbers of neutrons, which makes some uranium isotopes fissile.

Aircraft that contain depleted uranium trim weights for stabilizing wings and control surfaces (such as the Boeing 747-100) may contain between 400 and 1,500 kg of DU.

In a nuclear bomb you got highly enriched uranium that goes into critical mass and explodes with a force in the order of megatons. In a nuclear reactor we got low enriched uranium that is used as fuel in a reactor where neutrons are fired at the Uranium to cause nuclear fission or breaking of the Uranium atoms.

As of 2019, the U.S. has an inventory of 6,185 nuclear warheads; of these, 2,385 are retired and awaiting dismantlement and 3,800 are part of the U.S. stockpile. Of the stockpiled warheads, the U.S. stated in its March 2019 New START declaration that 1,365 are deployed on 656 ICBMs, SLBMs, and strategic bombers.

A nuclear weapon (also called an atom bomb, nuke, atomic bomb, nuclear warhead, A-bomb, or nuclear bomb) is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or from a combination of fission and fusion reactions (thermonuclear bomb).

Isotopes of uranium. Uranium (92U) is a naturally occurring radioactive element that has no stable isotope. ... All three isotopes are radioactive (i.e., they are radioisotopes), and the most abundant and stable is uranium-238, with a half-life of 4.4683×109 years (close to the age of the Earth).

An atomic bomb uses either uranium or plutonium and relies on fission, a nuclear reaction in which a nucleus or an atom breaks apart into two pieces. ... The hydrogen bomb relies on fusion, the process of taking two separate atoms and putting them together to form a third atom.

Nuclear fission produces the atomic bomb, a weapon of mass destruction that uses power released by the splitting of atomic nuclei. When a single free neutron strikes the nucleus of an atom of radioactive material like uranium or plutonium, it knocks two or three more neutrons free.

Released by the B-29 Bockscar, the 10,000-pound weapon was detonated at an altitude of approximately 1,800 feet over the city. The bomb had an explosive force (yield) of about 20,000 tons of TNT, about the same as the bomb dropped on Hiroshima.

—Different kinds of bombs were used on the two cities, that dropped over Hiroshima being a uranium-235 bomb, whereas the one used against Nagasaki was composed of plutonium-239.

['Uranium (92U) is a naturally occurring radioactive element that has no stable isotope. ... ', 'Naturally occurring uranium is composed of three major isotopes, uranium-238 (99.2739–99.2752% natural abundance), uranium-235 (0.7198–0.7202%), and uranium-234 (0.0050–0.0059%).']

As the RealLifeLore video above explains, on 6 August 1945, the Hiroshima bomb produced an explosion of 15 kilotons (or 15,000 tons worth of TNT) and three days later, Nagasaki sustained an explosion of 21 kilotons.

A Gold (Au) atom has 79 protons and 79 electrons. A typical gold atom has 118 neutrons, though there are 18 other radioisotopes discovered so far. 79 is its charge (atomic number), which is both its proton number and electron number.
