Most of the properties of materials are from the charged pieces that make them up -- the protons and electrons. Since adding neutrons wouldn't change the number of electrons or protons other isotopes would be almost identical for the purposes of chemistry, light, etc.
Some small differences might crop up in things that depend explicitly on the mass of the nucleus (e.g. sound propagation, density). But given adding a few neutrons in heavy nucleus is a change of order a percent or so in mass it isn't likely to be dramatic.
- zeristor 6y agoMy main question was are the only examples in Mercury, and Gold? AI, and Hg are next to each other on the periodic table, just on the metal / non-metal boundary, beneath them are the Rg, and Cn. Rg Roentgenium has a short half life, but seems to be tricky to make, it is expected to show some Relativistic properties though: https://en.m.wikipedia.org/wiki/Roentgenium https://en.m.wikipedia.org/wiki/Roentgenium Cn Copernicum, according to Wikipedia seems to show RQM effects it acting like a noble gas, albeit one with a half-life of at most 28s: https://en.m.wikipedia.org/wiki/Copernicium https://en.m.wikipedia.org/wiki/Copernicium If so why only these too? I’d expect there to be several others with mysterious properties too.
