Proctatium does not appear to be a recognized element or compound in scientific literature. It may be a typographical error or a fictional term. If you meant "protactinium," it is a radioactive element that was first isolated in 1913 by German chemist Frederick O. G. Giesel. Protactinium is formed naturally in trace amounts through the decay of uranium and thorium in the Earth's crust.
