More common than gold, uranium is abundant on Earth. But less than one percent of the naturally occurring element is useful ...

When Israeli aircraft recently struck a uranium-enrichment complex in the nation, Iran could have been days away from ...

Uranium has civilian uses that have nothing to do with weapons. For a bomb, the uranium needs to be a lot more concentrated.

Not that anyone asked, but uranium enrichment is certainly a newsworthy topic where a little science might be helpful. Here's ...

Israel is a nuclear armed state! Some claim it has 90-400 nuclear warheads and has not signed the Treaty on the ...

you need to know a little about uranium isotopes and about splitting the atom in a nuclear fission reaction. All matter is made of atoms, which in turn are made up of protons, neutrons and electrons.

Only 0.72% of it is uranium-235 with 92 protons and 143 neutrons (the remaining 0.01% are other isotopes). For nuclear power reactors or weapons, we need to change the isotope proportions.

To “enrich” uranium means taking the naturally found element and increasing the proportion of uranium-235 while removing uranium-238. There are a few ways to do this (including new inventions from ...

When uranium is mined from the earth, almost all of it—about 99.27%—is a type called uranium-238, which has 92 protons and 146 neutrons. A very small amount—only 0.72%—is uranium-235 ...

When we dig uranium out of the ground, 99.27% of it is uranium-238, which has 92 protons and 146 neutrons. Only 0.72% of it is uranium-235 with 92 protons and 143 neutrons (the remaining 0.01% are ...
