Question

Ryan is interested about the distinguishing
characteristics of metals. He collected samples of commonly-used household
materials such as copper wires, aluminum can and silver ring. He observed that these materials exhibit
similar physical characteristics. Write and describe the characteristics of a
metal observed by Ryan?

Answer 1

Answer:

Characteristics of metal:

- Good conductor of heat

- Good conductor of electricity

- Shiny surface

- Malleable

- Ductile

- High melting points

Answer 2

The characteristics of a metal observed by Ryan are written and described below:

1. Metallic lustre: Very first Ryan can observe that the surface of all three metals copper, aluminium, and silver ring have a shining surface.
2. Malleability: The metals can be beaten into thin sheets, and this property of metals is malleability. The aluminium can has a thin sheet of aluminium.
3. Ductility: Drawing the metals into thin wires, this property is ductility. Copper is drawn into wire here.
4. Hardness: Metals are generally hard. This can be observed by trying to cut the can or ring.
