• A. Both are sonorous.
• B. Both are poor conductors of heat.
• C. Most metals are hard and lustrous, while most non-metals are soft and dull.
• D. Metals do not conduct electricity while non-metals do.

Answer 1

Answer: (C)

Most metals are hard and lustrous, while most non-metals are soft and dull.

Metals are generally sonorous, and good conductors of heat and electricity. On the other hand, most non-metals are not sonorous and are bad conductors of heat and electricity.

Moreover, metals are generally hard and lustrous, and non-metals are soft and dull.

Examples of metals include iron, copper, aluminium. Examples of non-metals are carbon, oxygen, phosphorus.
