What are coinage metals ? Are they transition elements ? 

Text Solution

Verified by Experts

IB group elements copper, silver and gold are called coinage elements. In olden days these metals are used to prepare coins.
They do not have incompletely filled subshell in elemental form but they have partially filled d-shell in their chemically significant oxidation states. Thus they are transition elements.
