Question

Differentiate between metal and non metals on the basis physical and chemical properties

Answer 1

Answer:

Physical properties

Metals

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

Non Metals

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

Metals

Easily corrodible

Can lose electrons

Form basic oxides

Have low electronegativities

Good reducing agents

Non metals

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

Keep smiling☺☺☺

Answer 2

Answer:

Explanation:

Answer: Differences between metals and non-metals on the basis of their chemical properties.

                                      Metals

• Oxides of metal are basic in nature.

• Metals displace hydrogen from dilute acids.
• Metals form chlorides which are electrovalent or ionic compounds
• 4. they displace hydrogen from water

                                   Non-Metals          

•  Oxides of non-metals are acidic in nature.

• They cannot do so
• Non-metals form chlorides which are covalent compounds.
• They cannot do so
