Does Americium Occur Naturally?

Americium occurs naturally in uranium minerals, but only in trace amounts. The main source of the element is the neutron bombardment of plutonium in nuclear reactors.

Is americium natural or synthetic?

Americium, a silvery-white, synthetic element, is created during nuclear reactions of heavy elements. The element and its isotopes have very few but important uses including smoke detectors found in nearly all buildings and the potential to power future space missions.

Is Curium naturally occurring?

Curium is a member of a group of elements, the transuranic elements, that - with the exception of plutonium and neptunium - do not occur naturally on Earth. Curium is a hard, brittle, silvery radioactive metal that tarnishes slowly and which can only be produced in nuclear reactors.
