Answer:
Metals are generally malleable and ductile. Non metals are generally brittle and can break down into smaller pieces. ... Metals are good conductors of heat and electricity. Non metals are generally bad conductors of heat and electricity except graphite.
(a) Lustre They are lustrous, they shine. They are non-lustrous. Exception- Graphite, Iodine
(b) Malleability They are malleable, they can be drawn into sheets. Exception - zinc They are non-malleable. Exception - Carbon fibre
(c) ductility They are ductile, they can be drawn into wires. Exception - zinc, mercury They are non-ductile. Exception - Carbon fibres.
(d) tensile strength They have high tensile strength. Exception - zinc, mercury They have low tensile strength. Exception - Carbon fibres
(e) Sonority They are sonorous. They are not sonorous.
(f) Conduction of heat and electricity They are good conductors of heat and electricity. They are poor conductors of heat and electricity.
(g) Melting and boiling point They have a high melting and boiling point. Exception - Sodium, potassium, mercury They have a low melting and boiling point. Exception - carbon, silicon
(h) Density They have high density. Exception - sodium, potassium, calcium They have low density. Exception - graphite
