Americium: the essentials

Americium atoms have 95 electrons and the shell structure is 2.8.18.32.25.8.2. The ground state electronic configuration of neutral americium is [Rn].5f7.7s2 and the term symbol of americium is 8S7/2.

Americium: description  

The lustre of freshly prepared americium metal is whiter and more silvery than plutonium or neptunium prepared in the same manner. Americium is a component of the smoke detector above.

Americium appears to be more malleable than uranium or neptunium and americium tarnishes slowly in dry air at room temperature. Americium is a radioactive rare earth metal which must be handled with care to avoid contact, since it is a heavy α and γ emitter. It is named after America. The α activity of 241Am is about three times that of radium. Americium is available to qualified users in the UK and in the USA.
