After the second half-life of uranium, half of the original amount will remain. Therefore, if you start with 80 grams of uranium, after one half-life you would have 40 grams remaining, and after the second half-life, you would have 20 grams.

What Would happen if you had uranium in a enclosed container and exposed it to a large amount of electricity?

Being a metal Uranium would conduct electricity.


What is enriched uranium?

Enriched uranium is uranium that has had its U-235 isotope content elevated above what it would be when we refine natural uranium after recovering the metal from ore.We know that U-235 is the desired fissionable isotope of uranium, but it is the isotope U-238 that is present in over 99% of all the naturally occurring uranium we mine and recover. We have to put the uranium through a process to separate the U-235 from the U-238. As these two isotopes are chemically identical, it takes a mechanical process to separate them. After running the uranium through a process designed to take advantage of the difference in the mass of the two atoms, the industry will recover uranium with a very high percentage of the U-235 isotope, and this is called enriched uranium.If uranium is enriched to a point where there is up to about 20% U-235, it is low-enriched uranium. Above that 20% mark we see highly enriched uranium. Above about 85%, we call the product weapons-grade uranium. A link can be found below for more information.


Would you expect neodymium and uranium to have similar properties?

Uranium and neodymium are very different chemical elements.


What color is uranium in its liquid state?

Uranium is a silvery-grey metal in both solid and liquid state, However on exposure to air it produces a black uranium oxide on its surface, which would happen much faster to liquid uranium than to solid uranium.


Which dating technique would be best for a volcanic rock containing uranium?

Radiometric dating based on the decay of the uranium.

How many atoms in 1 gram of uranium?

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.


Why would you use liquid uranium?

Now liquid uranium has not applications.

If your body was reduced to chemicals how much would you cost?

If you weighed 68000 grams, 44200 grams would be oxygen, 12240 grams would be carbon, 6800 grams would be hydrogen, 2040 grams would be nitrogen, 1020 grams would be carbon, 816 grams would be phosphorous, you would have 136 grams each of chlorine, sulfur, and potassium, 68 grams would be sodium, 34 grams would be magnesium, and you would have about 136 grams of iron, cobalt, copper, zinc, and iodine combined, and 13.6 grams of selenium and fluorine combined. You do the rest.
