Neptunium

Neptunium is a toxic and radioactive heavy metal, which exists on earth only in extremely small traces. It was named after planet Neptune, the neighbour of Uranus, since the element is the neighbour of uranium in the periodic table. It is only used in nuclear technology, specifically for atomic batteries.
