Explanation:
Answer:
a)
Metals :-
Metals are sonorous
Metals are lustrous
Metals are ductile
Metals are malleable
Metals are good conductors of heat and electricity
Metals have high melting and boiling points
Metals form crystalline structure
Most of the metals are solids except mercury,gallium and caesium
Most of the metals are hard except Lithium ,Sodium and potassium
Non metals :-
Non metals are non sonorous
Non metals are non lustrous except iodine crystals
Non metals are amorphous except iodine crystals
Non metals are non ductile non malleable and bad conductors of heat and electricity
Non metals have less melting and boiling points
Non metals are solids liquids and gases
b)
(i) it's because of the small atomic weight of hydrogen
(ii) it's because when hydrogen is burnt , it liberates an electron causing pop sound
