In 1944, Seaborg inferred that the 14 elements heavier than actinium shared similarities with the element itself and belonged in their own family (the actinides). This sequence included the transuranic elements and showed where they fitted in the table.

This ‘Curie therapy’ was the first example of radiation-based cancer treatment, leading to the development of modern radiotherapy.

In a nuclear reactor, the chain reaction is controlled; in a bomb, it becomes a runaway process, releasing the nuclear energy in an explosion. 3-SECOND STATE Chemical symbol: U Atomic number: 92 Named: After Uranus, the planet discovered eight years before uranium 3-MINUTE REACTION Uranium has several isotopes, all of them radioactive.
