Basically, an isotope is the same element but with a different mass. Unprocessed uranium is mostly uranium-238. It only ...

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

When an atom breaks apart, it gives out energy and more neutrons, which can then split other atoms. Get enough atoms splitting and you have the chain reaction needed for a bomb blast ...

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.

99.27 per cent of it is uranium-238, which has 92 protons and 146 neutrons. Only 0.72 per cent of it is uranium-235 with 92 protons and 143 neutrons (the remaining 0.01 per cent are other isotopes).

For uranium, two main isotopes are important to understand: Uranium-238 (U-238) is the most common form of uranium found in nature, making up about 99.27% of natural uranium.

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% ...

The difference between uranium-238 and uranium-235. When we dig uranium out of the ground, 99.27% of it is uranium-238, ... That's because of the two main uranium isotopes, ...
