However the fuel used is about 95 percent U-238, simply because that is the result of enriching natural uranium to 5 percent…The U stands for Uranium which is a radioactive metal and the 238 stands for what number of isotope. It is very similar to U-235, which is used in nuclear reactors. Depleted Uranium, 0.2% U-235 99.8% U-238: Armor piercing antitank Gatling gun bullets and tank armor plate Highly Enriched Uranium, 93.5% U-235 6.5% U-238: Fission bomb cores Reactor Produced Uranium, 238 represents the atomic mass of Uranium.But now imagine that some geologic event disturbs things to make the lead escape.

The results from these zircons therefore plot along that straight line, establishing what is called a discordia. If a 1500-million-year-old rock is disturbed to create a discordia, then is undisturbed for another billion years, the whole discordia line will migrate along the curve of the concordia, always pointing to the age of the disturbance.

It occurs naturally as U-238 with a very small amount of U-235, when U-235 is refined out it is called depleted… Yes, it is used but the rest of the above answer is entirely wrong. Uranium's standard isotope (which is U-238) is composed of 92 Protons ( charges) and 146 Protons (- charges).

This tells you that a standard Uranium atom is negatively charged.

Dating a rock involves uranium-lead measurements on many zircons, then assessing the quality of the data.

Some zircons are obviously disturbed and can be ignored, while other cases are harder to judge.
