State three physical properties on the basis of which metals can be
distinguished from non-metals.
Answers
Answer:
Properties of Metals
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
