Chemistry of Metals and Alloys Questions

Multiple choice

Which metals have tendency to form compounds?

  1. more reactive metals

  2. less reactive metals

  3. both the above

  4. none of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

More reactive metals (like alkali and alkaline earth metals) have a stronger tendency to form compounds because they readily lose electrons to achieve stable electron configurations. Less reactive metals (like gold and platinum) are more stable in their pure form and resist chemical combination. Reactivity is directly related to compound-forming tendency.

Multiple choice

German silver used for making utensils is an alloy of _____.

  1. copper, silver, nickel

  2. copper, zinc, nickel

  3. copper, zinc, aluminium

  4. copper, nickel, aluminium
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

German silver (also called nickel silver) is an alloy of copper (50-70%), zinc (15-30%), and nickel (5-30%). Despite the name, it contains NO silver. The name comes from its silver-like appearance. It's corrosion-resistant and used in utensils, musical instruments, and jewelry.
