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.
What else can I help you with?
Predict the reaction between chlorine and potassium astatide?
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.
Astatine has 85 protons what is the atomic number?
The atomic number is the number of protons, so the atomic number of astatine is 85.
Why did it take longer to find astatine then any other of the halogens?
1. Astatine is an extremely rare chemical element, very difficult to identify in minerals. 2. The preparation of artificial astatine was dependent on the progress in nuclear physics and technology.
What type of element is astatine?
Astatine is an element with the symbol At.
How many electrons does one atom of astatine have in its outer shell?
Electrons per shell in astatine: 2, 8, 18, 32, 18, 7.
How many valence electrons does astatine have?
Astatine has 125 neutrons
What at the common compounds formed by astatine?
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.
Why did it take sixty years longer to discover astatine than all the other halogens?
1. Astatine is an extremely rare chemical element, very difficult to identify in minerals. 2. The preparation of artificial astatine was dependent on the progress in nuclear physics and technology.
What is astatine?
The color of the element astatine is unknown.
What odor does astatine have?
The odor of astatine is not known up today.
What is the charge of ions on Astatine?
Astatine is in the group 7A of the periodic table. The members of this group all have an ionic charge of -1, so At (astatine) will have a -1 ionic charge.
