In 1940, astatine was produced in a lab at the University of California by the three scientists named Carson, Mackenzie, and Segre. This element is classified as a semi-metal and has the atomic number of 85.

Fortunately it is impossible to found astatine in your home.


astatine can be found in no everyday objects. it is only found in Uranium :)


Astatine is an extremely rare chemical element, not found in common materials.


Astatine can be found in uranium and thorium minerals but in extremely low concentra-tions; the source of astatine is nuclear reactions between bismuth and alpha particles with high energy.


Astatine exist in nature very probable as compounds.


Yes, it is. All isotopes of astatine are radioactive. Only traces of a single isotope are found in nature.


astatine is found from uranium ore. http://www.wisegeek.com/what-is-astatine.htm has got some info... hpe it helped


no, it is most commonly found as a compound


It Can Be found In The Earths Crust, But In Very Small Amounts. It Can Also Be Found In Ores


Astatine is found naturally as a member of the radioactive decay series: uranium, thorium and actinium series; the chemical form is not excatly known.


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.

All the halogens, with the possible exception of astatine, are found in sea water.


The chemical formula for astatine is "At"


Due to the fact that the amount of astatine found in a whole kilometre of the earth's crust contains less than 50 mg of astatine, no accurate price can be made due to the fact that a very small of amount of an extremely radioactive material will be hard to make.


Astatine has 125 neutrons
