1. Naturally astatine is found in the decay series of uranium, thorium and actinium. 2. Artificially astatine is prepared by nuclear reactions between bismuth and alpha particles with very strong energy.
Artificially prepared in 1940 by: Dale R. Corson, Kenneth Rose MacKenzie and Emilio Segre Discovered in the natural decay series of radioelements in 1943 by: Berta Karlik and Traude Bernert.
Astatine is an element with the symbol At.
Astatine has 125 neutrons
Some common compounds formed by astatine include hydrogen astatide (HAt), astatine monochloride (AtCl), astatine monobromide (AtBr), and astatine monoxide (At2O). Due to the scarcity and radioactive nature of astatine, its compounds are not commonly studied.
The color of the element astatine is unknown.
