The density of gold is 19,320 kg/m3, which is higher than of uranium (18,800) and much higher than of lead (11,340). The armor-piercing ammo is made of uranium for its high density - golden bullets would work for this purpose even better.What is the name of the most radioactive isotope on the planet?Polonium 210. 210Po is extremely toxic, with one microgram being enough to kill the average adult (250,000 times more toxic than hydrogen cyanide by weight).210Po was used to kill Russian dissident and ex-FSB officer Alexander V.

Commonly used metals are considerably less dense - the density of iron is 7,870, lead 11,340 and mercury 13,456.Which chemical element has the symbol Ta?Tantalum was named by its discoverer, Swedish chemist Anders Ekberg for Tantalus, a Greek mythological figure, most famous for his eternal punishment in Tartarus. Tantalus was made to stand in a pool of water beneath a fruit tree with low branches, with the fruit ever eluding his grasp, and the water always receding before he could take a drink. Ekberg selected the name because the elment's inability to absorb acid recalled Tantalus' punishment to him.
