And there may be many others but they haven't been discovered
Three newly discovered elements were given names on Friday by the General Assembly of the International Union of Pure and Applied Physics at a meeting in London.
They are Darmstadtium, or Ds, which has 110 protons in its nucleus and was named after the town in which it was discovered; Roentgenium, or Rg, with 111 protons, named after the discoverer of X-rays Wilhelm Conrad Roentgen; and Copernicium, or Cn, which has 112 protons and is named after the Polish astronomer Copernicus, who disrupted the view that the Earth was the center of the universe.
I never realised that the Emergent Chaos Jazz Combo was into heavy metals 🙂
Oh, it won’t last very long.
