Question 1
Which of the following property is generally not shown by metals?
(a) Electrical conduction
(b) Sonorous in nature
(c) Dullness
(d) Ductility

Answer 1

1. Metals can be drawn into wires. So metals are ductile.
2. They are good conductors of electricity.
3. Metals produce ringing sound when beaten, i.e., metals are sonorous.
4. Metals have the quality of reflecting light from its surface due to which they are very shiny. Usually non metals are not that shiny, so dullness is the property of non metals.
Hence, Option (c) is correct.
