Answer
Amalgam is a mixture or an alloy of mercury with a number of metals or alloys such as sodium, zinc, gold, and silver, as well as some non-metals.
For example, Dental amalgam is a mixture of mercury and a silver-tin alloy. It is often used in dentistry as a filling material for cavities in teeth. The mercury acts as a binding agent that holds the other metals together to form a solid, durable material.
