Is tantalum a rare earth?
Here we’ll discuss a few actual rare metals, present in the earth in miniscule amounts but which have important applications nonetheless. 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.
