Question

Three differences between physical and chemical properties of metal and non metal

Answer 1

metal are ductile non metals are non ductile. metals are sonorous that is produce a ringing sound while non metals are non sonorous. metals are malleable they can be drawn into thin sheet non metal are nonmalleable

Answer 2

Physical properties of metals:

1. They are lustrous.

2. They are ductile and malleable.

3. Metals are sonorous.

Non- Metals

1. These are non lustrous except iodine.

2. These are brittle.

3. These are non snorous.

Chemical properties of Metals:

1. Metals form basic oxides.

2. Metals react with acids to form salt and hydrogen gas.

3. Metals are electropositive.

Non- Metals

1. They form acidic oxides.

2. They do not react with acids.

3. Non metals are electronegative.
