Question

Which of the following is the characteristic of non-metals?

• A. They are good conductors of electricity.
• B. They are good conductors of heat.
• C. They are ductile.
• D. They are insulators.

Answer 1

The correct option is D They are insulators.

Non-metals are the elements that mostly lack metallic attributes. They are soft and brittle so cannot be drawn or stretched into long wires. Instead, they break down into pieces on being hammered. They are non-ductile. Also, they are insulators and hence do not conduct heat and electricity.
