Relation to Platinum group?
The non-similarity of the iron group metals (meaning iron, cobalt and nickel in this case) to the platinum group and its causes should be explained. Normally you'd expect them to be chemically similar, since they are located in the same columns in the periodic system. -- 77.7.149.205 (talk) 13:32, 10 October 2010 (UTC)

What are the chemical similarities?
Many sources claim that the "iron triad" elements have "obviously" similar chemical properties; but I could not find a source that listed them. Help, please? (A couple sources say that they are ferromagnetic, and the only other element that is similar in that respect is the rare earth gadolinium. That is significant, but not really a chemical property...) --Jorge Stolfi (talk) 22:18, 1 April 2019 (UTC)

Verifying platinum metal minerals
I need someone who can verify what these minerals are 2600:1008:B12D:689C:CCCA:C906:BFF9:9115 (talk) 03:25, 24 January 2022 (UTC)
