Uranium forms almost instantaneously in supernova explosions.
Uranium is not a fossil fuel and cannot be a fossil fuel.
Depending on the size and type of the bomb and also on the enrichment installation available.
The half-life (time necessary for the disintegration of 50 % uranium atoms in lead stable isotopes) for uranium: Uranium 235: 7,038.108 years Uranium 238: 4,468.109 years
Milliards of years by natural radioactive decay.
Uranium is extracted from uranium ores.
Uranium is formed from...uranium atoms !
how long does it take to make a crayons
- By melting of metallic uranium. - By sticking sintered uranium dioxide pellets
Uranium is a donor of electrons.
You are orobably thinking of the small cylinders which make up the fuel rods. These are 10mm diameter and about 10mm long, and are packed end to end inside the zircaloy sheath to make a fuel rod. The material is uranium dioxide with the uranium enriched to about 5% U-235.
In the reaction238U + n-------239U-------239Np + e--------239Pu + eone atom of uranium become one atom of plutonium.
700 million years
As long as there are any uranium atoms. Since U-238 has a half-life of over a billion years, that can be a long, long time.
700 million (more exactly 703,8.106) years
We can obtain uranium from minerals; isotopes of uranium can be prepared as a result of nuclear reactions (the most important example is the isotope uranium-233).
U.S. law shows its perfectly legal to own up to 15 POUNDS OF PURE URANIUM. Some companies sell it in small amounts. It would take a mass factory to make a nuke which is not so easy to hide. Uranium 235 is the uranium for bombs, not PURE URANIUM. United Nuclear is a good place.
In order to make energy from uranium you have to split the atoms in the element.
Uranium is not used to make knives !
as long as it take for a fimble to make a cake
- Uranium don't contribute to global warming- Uranium don't release carbon dioxide
Billion of years; each isotope has a different half life.
The electron configuration of uranium is: - long: 1s22s2p63s2p6d104s2p6d10f145s2p6d10f36s2p6d17s2 - Short: [Rn]5f36d17s2
Uranium as a pure metallic element was obtained after the alchemic period; alchemists don't know uranium.
