The density of uranium is 18.90 grams per cubic centimeter.
1 cubic centimeter = 0.0610237441 cubic inch
So 1 cubic inch weighs 18.90 ÷ 0.0610 = 309.715 grams
1 ounce = 28.3495231 grams
So 309.715 ÷ 28.35 grams/ounce = 10.925 ounces or 0.6828 pounds
The atomic mass number of that isotope. So C14 has a molecular mass of 14 grams/mole U238, 238 grams/mole
Depends on the isotope. Most uranium found naturally is U238 and hence 238 g would be 1 mole. U235 used for fission and bombs would be 235g.
it is exactly 238.02891 u ± 0.00003 u or in other words you can write it as 395,256.10-24 grams
Element number 92 is Uranium and there are two main isotopes - U235 and U238. In U235 there are 92 protons so there are 235 - 92 = 143 neutrons. In U238 there are thus 146 neutrons
The term half life describes the rate at which the isotopes of a particular atom decay. Thus, if you have a lump of Uranium 238 (U238), then the atoms in the lump will decay at the same rate as the half life. If that lump was created four billion years ago and it consisted of 100% U 238, today the lump would be half U238 and half something else, mostly lead. That would go for both the atoms and the whole lump. If the lump consisted of 10% U238 today it would consist of 5% U238, and 95% something else. The fact that the U238 has a half life of 4 billion years only affects the Uranium and nothing else.
Yes, U233, U235, and U238 are all used as nuclear fuels.
U238 releases a small part called alpha radiation and a large part known as the decay product.
# I'm not clear what size pellet you mean. However for Uranium235 (the fissile isotope), if it is fully used up, 1 kg will give as much energy as 1500 tonnes of coal, ie 1,500,000 kg of coal, so that is the ratio, 1,500,000 to 1. Of course uranium as loaded into the reactor is actually about 4 percent U235, the rest U238 which is not fissile, so the U235 is 1/25 of the total weight of uranium, and if you mean the total uranium weight you therefore have to reduce this ratio by 25, and get 60,000 to 1.
The same name with a different atomic mass number. As an example U235 and U238 are two isotopes of Uranium
This means that the nuclear material is of a high enough concentration to fissile (allow for a fission chain reaction). This is because Uranium comes naturally as 99.3% U238, which cannot sustain fission, and .7% U235, which is what they want for the fuel. So they have to find away to pull away the U238 and leave the U235. As they concentrate the U235, it becomes concentrated enough so that it can sustain fission (too much U238 bogs down the reaction and will eventually end the fission). When it reaches this point of concentration, it is concidered reactor grade. Different elements have different needed concentrations to reach this level.
Only in the mass of the nucleus, due to 3 extra neutrons in U238.
It is a dating method in geology based on natural fission of U238 to determine the atomic displacement (tracks) counts to determine age of material or volcanic deposits.
