Rubidium is actually one of our commoner elements and depending on which information source you look at, it is about the 16 th most abundant element in the earth's crust, with a concentration somewhere around 90 parts per million. Although it is relatively abundant compared with other elements such as copper, it is not found in a pure state but ...
