Nuclides and ions
3 nuclides, 1 ionsA nuclide and an ion of an element are flow objects in their own right — Co 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.

40 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.
