Americium is not found naturally in significant amounts and is typically produced in nuclear reactors or particle accelerators by scientists. It is a synthetic element created through nuclear reactions involving plutonium.
Americium was obtained for the first time in USA, by Glenn Seaborg, Ralph James, Leon Morgan, Albert Ghiorso, year 1944.
Like all other metals except for mercury, americium is solid at room temperature.
Either Tin (Sn) or Aluminum (Al) are used in foil wrap. Hope this helps!
