WebJan 18, 2024 · It is believed that astatine can produce salts if it was left to react with metals. It can also react with hydrogen to form a halogen acid. Astatine Uses What is astatine used for? The... 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…
