Radon Rn

A nuclide and an ion of an element are flow objects in their own right — Rn and each of the records below are separate substances, resolved separately and characterised separately. What holds them together is a statement on the child naming this element as its parent, which is why they are drawn under it rather than beside it.

• Radon 86 fo-37b91965500c706c
  • Nuclides 2
    • Radon-220 220Rn 12 flows

      Half life 55.6 s ± 0.1. Decay α=100%; 2β- ?. chemlin

    • Radon-222 222Rn 12 flows

      Half life 3.8215 d ± 0.0002. Decay α=100%. chemlin

    61 further nuclides are known and are not in this list: they are too short-lived for an inventory to carry, and their absence is a decision rather than a gap.
