Nuclides and ions
2 nuclides, 0 ionsA nuclide and an ion of an element are flow objects in their own right — Cm 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.
