Answer 2

➩ Non-metals are Non-malleable or Brittle:- Non-metals break into pieces when stretched. For example, sulphur and phosphorous are brittle non-metals

➩ Non-metals are Non-ductile:- Non-metals cannot be drawn into thin wires i. e. they broke into pieces when stretched

➩ Non-metals are Bad Conductors of Heat and Electricity:- Generally Non-metals are bad conductors of heat and electricity because they do not have free electrons responsible for transfer of heat and electricity

➩ Non-metals are non-lustrous and cannot be polished

➩ Non-metals may be solid, liquid or Gases at room temperature

➩ Non-metals have low melting and boiling points as compared to metals

➩ Most of solid metals are soft

➩ Non-metals are not strong

➩ Non-metals are light substances
