But what is there the least of on Earth?

There is very little gold and platinum. That is why they are valued so highly. But it is a curious paradox that gold was the first of the metals to become known to man. Platinum was discov¬ered before oxygen, silicon or aluminium had ever been heard of.
The noble metals possess a unique feature. They do not occur in nature as compounds but in the native state. No effort is required to smelt them from their ores, that is why they were found on Earth, precisely found, so very long ago. We could rightly call them ghost elements.
The geochemists tell us that the amount of polonium on Earth is only 9600 tons; the amount of radon is still smaller, 260 tons; there is 26 thousand tons of actinium. Radium and protactinium are giants among the ghosts: their amount is about 100 millions tons, but compared to gold and plati¬num this is a very small quantity. As to astatine and francium, they can hardly be called even as ghosts, because they are still less material. The terrestrial reserves of astatine and francium are measured, ridiculous though it sounds, in mil¬ligrams. The name of the rarest element on Earth is astatine (69 milligrams in all of the Earth´s crust). No further com¬ments are necessary.
