Question

state any five physical properties on the basis of which metals can be distinguished from non metals 2. state any three physical and two chemical properties to prove that copper is a metal​

Answer 1

Answer:

Metals

1- metals are hard and rigid.

2- metals have high density.

3- metals are strong and have high tensile strength.

4-metals are sonorous.

5-metals are malleable.

Non- Metals

1- non metals are generally soft and brittle.

2- non metals have low density.

3-non metals have low tensile strength.

4- non metals are non sonorous.

5- non metals are non malleable.

Answer 2

Answer:

1) METALS

1. They are lusturous
2. They are sonorous
3. They are malleable
4. They are ductile
5. They are good conductors of heat and electricity

NON METALS

(Opposite to all points mentioned above )

2) PHYSICAL

• Hard
• Good conductor of electricity (used for making wires )
• Ductile ( can be drawn into thin wires)

CHEMICAL

• A basic oxide is formed ( metal oxides are basic in nature )
• It displaces less reactive metals
