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)
