Telluride (chemistry) - Wikipedia

The acid hydride of tellurium, hydrogen telluride, H2Te, is an unstable compound that decomposes to tellurium metal. It is strongly acidic, dissociating into a hydrogen telluride ion (HTe−) in aqueous solutions. Like its sulfide and selenide counterparts, the Te2− anion only exists in aqueous solutions in basic conditions.
