Approximately 15-25 kg of highly enriched uranium or 6-8 kg of plutonium is typically used in a 100-kiloton bomb. These materials undergo a fission chain reaction to release a huge amount of energy in a nuclear explosion.
In light water reactors the new fuel has about 4 to 5 percent U-235, which is the fissionable part, the rest being U-238. In some countries mixed oxide fuel is used (MOX) which contains some Plutonium as well as U-235, but the fissionable content is much the same. Heavy water or graphite reactors can use natural uranium, which contains 0.7 percent U-235.
a simple pipe bomb can probably be built for $20.
To make a fission atomic bomb you just take either uranium or plutonium, which are fast-fission materials and find a way to smash the soul out of them so they can make neutrons to continue the chain reaction. You either just take some fissionable uranium, make a bullet out of one and a ball of the other, build a cannon-shaped bomb that shoots the bullet of uranium into the ball of uranium at the end of the barrel - and boom. To make the second kind, you need some plutonium. Plutonium is easy to obtain but it is extremely hard to make into a bomb, because if you shoot two masses of plutonium together like the uranium bomb style, they fission so much easier that they start reacting before they touch and blow themselves apart before anything can fission, so you will need to make a ball of plutonium crush in itself using a shock wave made by a explosion. You surround a ball of fissionable plutonium with explosive stuff. When the surrounding explosives goes boom, the shock waves made by the explosives hits the ball. This causes the plutonium to supercompress itself together - and boom.
Fission bombs, especially of high yield are unstable and susceptible to a failure mode called "fizzle" in which the neutron chain reaction begins while the fissile material is still in a subcritical configuration. This simply causes the bomb to heat rapidly to the melting point, producing no useful nuclear yield. The maximum theoretical yield of a pure fission bomb that would not just "fizzle" is estimated to be about one megaton. The largest actual yield of a pure fission bomb was the 500 kiloton Ivy King test of 1952, using a hollow spherical uranium-235 core implosion assembly design with a boron-aluminum alloy chain filling the hollow core to prevent the large amount of uranium from undergoing an accidental predetonation/"fizzle" due to stray neutrons or spontaneous fission neutrons (the chain was rapidly removed by a motor shortly before detonation of the explosive lenses). Fusion bombs (aka hydrogen bombs) have no theoretical limits on yield, you can add as much fusion fuel as needed with no concerns over instability or "fizzle". They are triggered by small fission bombs that create the high temperature and pressure conditions needed to start fusion. Overall the cost/kiloton ratio is lower for a fusion bomb than a fission bomb (although the design is far more complicated).
The most powerful type of nuclear bomb is the hydrogen bomb, also known as a thermonuclear bomb. These bombs use a two-stage process, with an initial fission reaction triggering a fusion reaction, resulting in a much larger explosion compared to atomic bombs.
Probably approx. 40 kg of enriched uranium.
This is hard to compute. The 22 kiloton MK-III Fatman had 6.2 kilograms but of this only a little over 700 grams fissioned. For 1 kiloton you would need roughly 33 grams to fission. But how much more you would need to get the bomb to work reliably depends on too many tricky design details (most classified) to tell. Assuming the same material efficiency as the MK-III, a total of roughly 282 grams would be needed. However this amount is so far below criticality that a superefficient implosion assembly system would be required as well as gas boosting to get that small a yield.I would guess, without access to classified information, that a basic pure fission 1 kiloton bomb would need between 2.5 kilogram to 5 kilogram of plutonium to fission the roughly 33 grams needed for that yield.Material efficiency becomes real bad below about about 10 kilotons unless gas boosting is used. Even the MK-IIIs material efficiency of about 10% is low by today's standards, but the figure is still a good starting point, especially as it is not classified.
The bomb did not have tnt. The atomic power is measurred using tnt was the base. TNT is a unit of energy equal to 4.184 gigajoules, which is approximately the amount of energy released in the detonation of one ton of TNT, and a bomb with one kiloton has the blast compared to one ton of tnt.
Pretty much any radioactive material can be used.
A Kiloton of TNT is not really a measure of weight but of explosive force. A kiloton of TNT would would weigh 1000 metric tons or about 2.2 Million pounds. But a kiloton of water, feathers, bricks.. would also weigh 2.2 Million pounds. A kiloton of TNT has the energy of 4.2 × 1012 joules or 4 Billion BTU's which would be enough energy to raise the temperature of 2 Million tons of Water 1 degree F.
An atomic bomb is a nuclear weapon. A nuclear fusion bomb, (hydrogen, is usually much stronger than a nuclear fission bomb (uranium or plutonium). The weapons detonated in Japan during WWII measured about 15 kilotons equivalent of TNT. Today, most nuclear weapons are measured by megaton (1000X kiloton) equivalents up to a bomb built by the Russians with a possible yield of 100 megatons.
How much power is in this substance? Is it like cocaine, or fissionable material? I'd recommend concrete, or Jell-O.
Basically, a conventional bomb uses a chemical explosive as the source of its destructive power. A nuclear weapon uses nuclear material to create an explosion. A nuclear explosion is much larger, and also emits ionizing radiation. A chemical weapon does not emit any radiation. A nuclear weapon's yield is measured in Kilotons (thousand tons). In very simplified terms, this means that a nuclear weapon with a 475 kiloton yield produces an explosion comparable to 475,000 tons of TNT (TNT is a chemical explosive). That's A LOT of TNT and it would take up a bit of space. A nuclear weapon with this yield may only be a few feet long and a foot wide, and the actual nuclear material may be the size of a grapefruit.
1 Kiloton would be 1000 metric tons or 1000 x 32150746 troy oz or 32150746000 troy oz. If gold traded at $1300 per oz total value of 1 Kiloton of Gold would be 41.796 TRILLION dollars or about 2.45 times the total US National Debt.

The atomic bombs are nuclear weapons that use a nuclear chain reaction to create a Hugh explosion. The by-product of the nuclear blast is radiation.Atomic explosion is created by setting off a lot of dynamite around a core of nuclear material. The blast compresses the material together and makes it unstable.A hydrogen bomb is a much more powerful bomb. It is the result of a small nuclear explosion that compresses more powerful radioactive material together and thus creating an explosion that is 100 times greater than an atomic bomb.
