Americium | '''Americium''' is a [[radioactive]] [[chemical element]] that is classified as a [[transition metal]] and an [[actinide]]. It is the most commercialized and publicly used radioactive element in the [[periodic table]] with one of its main uses being an important component in household smoke detectors that help detect the presence of fires. | ||

Americium looks like a | Americium looks like a silvery white synthetic metal. When Americium is left out, it begins to tarnish in the dry air, and is resistant to alkalis. Americium is seen to be more dense than lead had its own distinct color to it. Americium possibly can be found on earth although only in fragmental amounts that could have been made in the past when there was huge groups of uranium when and then nuclear reactions could take place. Americium-243 is made from the release of isotopes from Plutonium-239 in the nuclear reactions. <ref>Americium Properties[http://www.lenntech.com/periodic/elements/am.htm Physical properties on Americium]. ''Lenntech''. Web. November 3 2011.</ref> Americium has a lot of chemical properties and is in a lot of mainstream products, so it has been used a lot, and has been seen as a staple in a lot of processes such as energy from nuclear reactors, as well in our households as fire alarms. | ||
