Less reactive than iodine, astatine is the least reactive of the halogens. Its compounds have been synthesized in nano-scale amounts and studied as intensively as possible before their radioactive disintegration. The reactions involved have been typically tested with dilute solutions of astatine mixed with larger amounts of iodine. Acting as a carrier, the iodine ensures there is suffici… WebFinally, radiolysis from astatine nuclei could sever the H–At bonds. Additionally, astatine has no stable isotopes. The most stable is astatine-210, which has a half-life of approximately …
