Question

name the metals
and
non metals its physical property and chemical property and its suse

Answer 1

Answer:

Different elements have different chemical and physical properties.

CHEMICAL PROPERTIES:

Metal: 1. Malleable and ductile.

2. Good conductors of heat and electricity. ( Lead exception)

3. They react with air and produce metal oxide.

4. Density of metals are always high.

Non metals: 1. Unlike metals they aren't malleable and ductile.

2. They are poor conductors of heat and electricity. ( Exceptional graphite and gas carbon ).

3. Non metals do not react with air in room temperature.

4. Density of non metals are low.

PHYSICAL PROPERTIES:

Metals: 1. Lustrous

2. High melting point.

3. Opaque as thin as sheet.

4. They are hard.

5. Have tensile strength

6. Sonorous

Non metals: 1. Have high electronegativity.

2. Have high ionisation energies.

3. They are insulators.

4. They are dull ( do not lustre ).

5. They are weak and brittle.
