Answers
Physical properties of 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
Chemical properties of metals
Easily corrodible
Can lose electrons
Form basic oxides
Have lower electronegativities
Good reducing agents
Physical properties of 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 of 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
1)They are lustrous
2)They are malleable
3)They are ductile
4)They are good conductors of heat and electicity.
5)ex-gold,iron etc.
》》Non metals
1)They are not lustrous
2)not malleable
3)not ductile
4)Not good conductors of heat and electricity.
5)ex.-chlorine,bromine etc.
