Question 1

What are the properties of non-metals?

Answer 1

Non-metals are typically brittle, poor thermal conductors, and have little or no metallic lustre.

Question 2

How do non-metals conduct heat?

Answer 2

Non-metals do not absorb or transfer heat well.

Question 3

What is the appearance of non-metals?

Answer 3

Question 4

What is an example of a non-metal used in glass?

Answer 4

Glass is mostly made up of a mineral called silica (SiO2), which is made of silicon (Si) and oxygen (O).

Because glass is made from non-metals, it does not conduct heat very well, making it useful for lab equipment.

Answer 5

Metals are lustrous, while non-metals are non-lustrous.

Answer 7

Non-metals are non-ductile.

Question 8

How do non-metals conduct electricity?

Answer 8

Non-metals are poor conductors of electricity.

Question 9
