Which term denotes a non-mercury alloy composed of gallium, indium, and tin?

• A. Galloy
• B. Mercury Alloy
• C. Silver Alloy
• D. Gold Alloy

Answer: (A)

The concept here is recognizing a non-mercury alloy made from gallium, indium, and tin. When gallium, indium, and tin are combined, you get a low-melting, non-toxic metal alloy often used as a mercury substitute in thermometers and other devices. The term used for this Ga–In–Sn alloy in the question is Galloy, which denotes that specific alloy composition. It’s distinct from a Mercury Alloy, which would involve mercury itself, and from Silver Alloy or Gold Alloy, which are based on silver or gold and do not refer to the gallium–indium–tin system.
