Why do the three most stable elements, iron, cobalt and nickle, also have magnetism? Does their stability have something to do with it, or is it just a coincidence?

I'd suggest reading up on remanence and hysteresis. Gives pretty good ideas why

Ok thanks. Those terms are new to me

They relate to the stability of the polarity of the electrons attached. Don't take any clowns word for it. I'll give advice and let you decide.

I am sure sidewalker will have to correct me as usual, but I am not sure what 'most stable'means. Do you mean 'least chemically reactive' or 'least radioactive'? Either way I am not sure it would be entirely true.

But if you did mean 'least radioactive' then it would be largely a co-incidence because radioactive stability is a property of nuclei and magentism a property related to the surrounding electrons.

You ask intereting questions, j6.... keep it up!

Just coincidence.

They are stable nuclei because they have high binding energy in the nucleus.

They are magnetic due to the motion of their electrons, which are way outside the nucleus and do not affect nuclear bond energies.

Magnetism is made my moving or spinning charges. In most elements the motion of the electrons is such that the magnetism from all the electrons added together is very nearly zero. In Fe, Ni and Co there is one electron which does not have its magnetism cancelled out by the motion of the other electrons in the atom.
