The rarest stable metal is tantalum. The rarest metal on earth is actually francium, but because this unstable element has a half life of a mere 22 minutes, it has no practical use. Tantalum, on the other hand, is used to make capacitors in electronic equipment such as mobile phones, DVD players, video game systems, and computers.
