      I’m not sure there is one single element. It depends on how much of the element and in what quantity. The most dangerous ones are most often thought to be Plutonium and Polonium.

      For polonium it is thought that if a 500 gram peice was disintegrated to dust and breathed in it would be toxic enough to kill 2 million people.

      While if you eat Polonium, one gram would provide enough poision to kill 10 million people
