Correct Answer - Option 4 : Alloy of mercury and any other metal
Concept:
- Alloys are substances which possess metallic character and are obtained by mixing of metal with another metal or another element.
- Either the mixture/alloy of mercury (Hg) with any other metal is called an amalgam whereas Tungsten, Platinum, Iron, and Tantalum are exceptions that do not form an amalgam.
- The alloys of mercury with any other metal are termed as amalgams and depending upon the proportion of mercury, they can be liquid, paste or solid in nature.
- One of the best examples of Amalgam is a mixture of mercury and silver which is used by the dentist for a dental filling.

From the above explanation, we can see that amalgams are an alloy of mercury and other metal like zinc copper magnesium except iron
Hence it is conclude that Amalgam is the alloy of mercury and any other metal.
