Gold is inert.
Silver is used an antibiotic.
Copper supplements zinc as an enzyme metal.
Chrome is used in the insulin-making process.
Splitting the heavy metal group may not be necessary because only a thin line exist between their beneficial effects and the toxicity so they should still be treated as one.
Paracelsus stated already centuries ago, that only the dosis determines whether something is a poison or not.
