Thanks! That's very helpful, and shame on me for not visiting Wikipedia first. That said, the error bounds listed on Wikipedia for a model-generated guess at melting temperature, etc. are gigantic. At room temperature, copernicium might be a liquid, unless it's a gas or a solid. I appreciate the audacity of researchers in trying to work up some guesses about physical properties even though the available samples are far too tiny and short-lived to get any lab confirmations. But articles like OP make it seem as if we've got well-tested insights. We don't. We're not nearly there yet. It's very loosely anchored guesswork.
