Except for astatine, the members are found in combined state in considerable quantities in nature.
Astatine is the element at the bottom of Group VII.
The least stable ground state isotope is astatine-213, with a half-life of 125 nanoseconds.
The halogens are a group of chemical elements that includes fluorine, chlorine, bromine, iodine, and astatine.
Solvent radiolysis due to the cumulative effect of astatine decay citation is a related problem.
All isotopes of francium decay into either astatine, radium, or radon. [2].
The isotopes of francium decay quickly into astatine, radium, and radon.
The bulk properties of astatine are not known with certainty.
The halogens are fluorine, chlorine, bromine, iodine, and astatine.
There is no material safety data sheet for astatine.
