Which one of the following is a coinage metal
Correct answer: B. Cu
- A. Pd
- B. Cu
- C. Cd
- D. Hg
Explanation
Copper, silver and gold form group IB and are called the coinage metals because their unreactivity and durability made them the traditional choice for currency. Palladium is a platinum group metal, and cadmium and mercury sit in group IIB with completely filled d subshells. All four are d block elements, which is what makes the distractors plausible.
This question appeared on the UHS MDCAT 2025 paper, which you can sit online with every answer explained.

About Electronic Structure of d-Block Elements
The electronic structure of d-block elements covers the filling of the (n-1)d and ns orbitals, general electronic configurations, and the exceptions shown by chromium and copper. It explains how partially filled d orbitals produce variable oxidation states, coloured ions, magnetic behaviour and complex formation, while distinguishing transition elements from elements with completely filled d subshells.
