At2(g) is the formula for gessoes astatine.
Astatine could potentially replace the chlorine in potassium chloride to form astatine chloride and potassium. The reaction would likely be very rare and unstable due to astatine's radioactivity and scarcity.
Cl2 + 2KAt arrow 2KCl +At2 Chlorine + Potassium Astatide arrow Potassium Chloride + Astatine This happens because Chlorine is more reactive than Astatine so the chlorine displaces the Astatine to produce Potassium Chloride and Astatine.
The atomic number of astatine (At) is 85.The atomic weight of At is 210 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
The element with the symbol At is named astatine.
Less than one ounce of astatine exists on Earth. It was discovered by D.R. Corson, K.R. MacKenzie and E. Segre in 1940.
Astatine because it was first discovered in Alabama
Astatine is an extremely rare element - the rarest, very difficult to be identified in natural products; astatine was discovered first time by nuclear reactions between bismuth and high energy alpha particles in 1940 and in 1943 was discovered between the decay products of uaranium, actinium and thorium series.

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.

The Latin language name of astatine is astatium.
Astatine has 85 protons.
