What elements in amalgam make it strong?

Tin and zinc
Silver and copper
Mercury and silver
Copper and zinc

The correct answer is: Silver and copper

Silver and copper are the elements in amalgam that make it strong. Amalgam is a dental filling material that has been used by dentists for over 150 years. Silver gives amalgam its strength, while copper helps with corrosion resistance and improved strength. When these two elements are combined, they create a durable and long-lasting material that is well-suited for dental restorations. Tin, zinc, and mercury are also components of dental amalgam, but they do not contribute significantly to its strength compared to silver and copper.
