  • U-235 18.4Kg (a sphere 12.6cm diameter) will do, probably less.
  • P-239 6.4Kg (a sphere 9.2cm diameter) will do, probably less.

How much uranium is usually in a nuclear bomb?

Cca. 50 kg of highly enriched uranium. Now nuclear bombs use plutonium, not uranium.


Whats the difference between nuclear chemistry and nuclear energy?

Nuclear energy is, primarily, the controlled (or, in a bomb, the uncontrolled) release of binding energy (Strong Atomic Force) in the nucleus of an atom by the process of fission or fusion. All nuclear power plants and the Atomic bomb use fission. The Sun and the Hydrogen bomb use fusion1. Nuclear chemistry, on the other hand, is the interrelationship between electron fields of various atoms as they interact to form various compounds, releasing and/or absorbing energy as they do so. Instead of the Strong Atomic Force, the electron field participate in the Electromagnetic Force, one of the other three primary forces. (The other two being the Weak Atomic Force, and Gravity.) ---------------------------------------------------------------------- 1Technically, the Hydrogen bomb also uses fission. It requires so much energy to initiate the fusion reaction that we use an Atomic bomb to set off the Hydrogen bomb.

What materials are used in nuclear weapons and bombs?

The question that you are asking in itself is quite broad as there are many types of nuclear weapons and bombs.. However, there are certain similarities to all of these weapons that are necessary to become nuclear. The materials themselves have to be able to produce a high amount of energy to be able to create that amount of destruction. If you have a chance to look at a periodic table, you'll notice the Hydrogen atom at the very beginning. The most popular type of nuclear bomb is the Hydrogen bomb, in which you take a hydrogen atom, and split it up into smaller parts.. However, this in itself takes huge amounts of energy and the energy released from this exothermic (energy-releasing) reaction is why it's so devastating. There's not really much materials used in a nuclear weapon other than a shell to hold the parts together upon needed release, and a machine or something of that nature to bombard the hydrogen atoms to make them split and a supply of hydrogen atoms themselves in order to make a hydrogen bomb. Now that's just one type of bomb...

Where were the first nuclear bombs dropped?

A nuclear bomb has never been dropped. It was an atomic bomb that was dropped on the Japanese cities Hiroshima ans Nagasaki. An atomic bomb is a nuclear weapon. Nuclear bombs have much more impact than atomic bombs, and could potentially end the World if a nuclear war was started.

How much do nuclear bombs weigh?

The weight of a nuclear bomb depends on the bomb. Deliverable nuclear bombs have been built with weights as small as 50 pounds to as large as 30 tons. The first hydrogen bomb built (Ivy Mike test Sausage device) weighed 54 tons, but was never intended as a deliverable bomb (including the cryogenic equipment needed to keep its deuterium-tritium fusion fuel liquid the complete setup weighed 82 tons).
