Talk:Halide

Tennesside and Astitide

The article mentions a theoretical tennesside. It seems that astitine is considered a metalloid, so maybe with properties significantly different from other halides above it. I don't see any indication whether there should be At₂ molecules in the solid form. Even less obvious that Ts behaves like other halogens forming Ts₂, or has a Ts^- ion forming ionic crystals. Otherwise, it would be interesting to have a crystal of FrAt or FrTs, rare and expensive alkali halides. Gah4 (talk) 21:21, 23 November 2019 (UTC)
