> A little physics: it is an pure natural element. It's symbol is Ta. It is found in the mineral called Tantalite and in other forms combined with oxygen. Its density is very high, almost as much as gold, its melting point is exceeded only by 3 elements (carbon, rhenium and tungsten) and it exceeds 3000°Celsius!
