I WONDER - What Are Non-metals?

Non-metals have unique abilities and are generally poor conductors of heat and electricity. Despite this, they play vital roles in our lives. Oxygen is crucial for breathing and combustion, while carbon is versatile, forming substances like graphite and diamonds. Non-metals are often used as insulators in electrical appliances to prevent unwanted electrical currents.

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

• They are magnetic.

• They are poor conductors of heat.

• They conduct electricity well.

• They are shiny.

Why is oxygen considered vital for life?

• It is a good conductor of electricity.

• It is essential for breathing.

• It is used as a fuel.

• It is used in making jewelry.

What makes carbon a versatile element?

• It forms both graphite and diamonds.

• It is always shiny.

• It is a good insulator.

• It is used in electrical appliances.

In what way are non-metals used in electrical appliances?

• As decorative elements.

• As insulators to prevent unwanted currents.

• As sources of light.

• As conductors to enhance current flow.

What is the primary role of non-metals in electrical appliances?

• To conduct electricity efficiently.

• To prevent electrical currents from going where they shouldn't.

• To enhance the appliance's appearance.

• To increase the appliance's weight.
