e/Astatane

Information
has gloss	eng: Astatane, also known as hydrogen astatide, astidohydrogen, or hydroastatic acid, is a chemical compound with the chemical formula HAt, consisting of an astatine atom covalently bonded to a hydrogen atom. This chemical exhibits properties very similar to the other four hydrogen halides, and is in fact the strongest acid among them, however is limited in use since it will readily decompose into elemental hydrogen and astatine. Because the atoms have a nearly equal electronegativity, and s the At+ ion has been observed , dissociation could easily result in the hydrogen carrying the negative charge. Thus, an astatane sample can undergo the following reaction:
