What is the second rarest element?
Characteristics: Francium is a heavy, unstable, radioactive metal with a maximum half-life of only 22 minutes. It has a low melting point (27 oC, 81 oF) and, if enough of it could be accumulated, it would be liquid in a warm room. Francium is the second rarest element in the Earth’s crust, next to astatine.
