Americium is a shiny radioactive metal and one of the actinides. It was discovered in the United States in the middle of the last century and named after the continent. It has no biological essence and is very toxic to all living organisms. In extremely small amounts this element can be spotted in uranium ores and minerals. But it can be produced in labs, in very small amounts which are only about a few grams a year. Americium is used for producing nuclear energy as well as in smoke alarms. This radioactive chemical element is considered to have a huge potential for being used as a source of fuel for spaceship batteries and chargers.
