List of the 10 Heaviest Metals (Density and Atomic Weight)

Uranium–lead dating, abbreviated U–Pb dating, is one of the oldest and most refined of the radiometric dating schemes. It can be used to date rocks that formed and crystallised from about 1 million years to over 4.5 billion years ago with routine precisions in the 0.1–1 percent range. The method is usually applied to zircon. This mineral incorporates uranium and thorium atoms into its crystal structure, but strongly rejects lead when forming. As a result, newly-formed zircon crystal… WitrynaFrom a non-proliferation standpoint, uranium enrichment is a sensitive technology needing to be subject to tight international control.
