Reminded me of https://en.wikipedia.org/wiki/Island_of_stability https://en.wikipedia.org/wiki/Island_of_stability

  Wait - the island of stability can be for more than a year? That's mindblowing. I wonder what the properties of these huge elements are.

    Very heavy elements tend to “break” the periodicity of the periodic table a bit, because there are so many inner-shell electrons shielding the nucleus, and because of odd relativistic effects. https://en.wikipedia.org/wiki/Relativistic_quantum_chemistry https://en.wikipedia.org/wiki/Relativistic_quantum_chemistry

      That makes me wonder - if gold's color can be explained via theoretical effects, can we predict the color of elements which don't exist in bulk and/or decay rapidly? Are any of them theoretically unusual and interesting?
