I WONDER - What Is A Metal?

Metals are strong, shiny materials that conduct heat and electricity well. They include iron, gold, and aluminium, each with specific uses. Metals are malleable, allowing them to be shaped without breaking, and ductile, enabling them to be drawn into wires, essential for electrical applications.

Which of the following is NOT a characteristic of metals?

• They are poor conductors of electricity.

• They are shiny.

• They conduct heat well.

• They are generally strong.

Which metal is commonly used in construction?

• Gold

• Iron

• Aluminium

• Copper

What does it mean when a metal is described as malleable?

• It can conduct electricity.

• It can be bent and shaped without breaking.

• It can resist corrosion.

• It can be melted easily.

Why is ductility an important property for metals?

• It enables metals to be stretched into thin wires.

• It makes metals resistant to rust.

• It allows metals to be used in construction.

• It allows metals to be used in jewelry.

Which property of metals is crucial for making electrical wires?

• Strength

• Malleability

• Ductility

• Shininess
