Question

b) Write the differences between the properties of metals andnon metals.​

Answer 1

Answer:

Physical Properties of Metals

Some physical properties of metals are listed below.

Shiny (lustrous) in nature

Metal is a good conductor of electricity and heat

Density and melting point is high

Mouldable (Malleable)

Ductile

At room temperature, it is in solid form except for mercury

Opaque

Chemical Properties of Metals

Some chemical properties of metals are listed below.

Easily corrodible

Can lose electrons

Form basic oxides

Have low electronegativities

Good reducing agents

Properties of Non-Metals

Physical Properties of Non-metals

Some physical properties of non-metals are listed below.

Poor conductors of electricity and heat

Non-Ductile metals

Brittle solids

Maybe solids, liquids or gases at room temperature

These are not sonorous

Transparent

Chemical Properties of Non-metals

Some chemical properties of non-metals are listed below.

The number of electrons in the outer shell is generally 4-8

Easily gain or lose valence electrons

Form acidic oxides whenever they come in contact with oxygen

High electronegative elements

Great oxidizing agents

Answer 2

Answer:

Metals

• Metals have lustre. Mercury and gallium are an exception.
• Metals are solids at room temperature. Mercury is an exception being liquid.
• Metals generally possess the property of hardness.
• They are ductile and malleable.
• Metals are good conductors of heat and electricity.

Non-metals

• Non-metals do not have lustre, Iodine and diamond are exceptions.
• Non-metals are either solid or gaseous. Bromine is an exception being in a liquid state.
• Non-metals do not possess the property of hardness.
• They are non-ductile and malleable.
• Non-metals are bad conductors of heat and electricity except graphite.
