Answer 1

Answer:

Physical properties

MetalsNon-metalsShinyDullHigh melting pointsLow melting pointsGood conductors of electricityPoor conductors of electricityGood conductors of heatPoor conductors of heat

Answer 2

Physical properties of a metal are:-

1)high melting points.

2)good conductors of electricity.

3)good conductors of heat.

4)high density.

5)malleable.

6)ductile.

Physical properties of a non-metal are:-

1)Poor conductors of electricity

2)Poor conductors of heat

3)Low density

4)Brittle

Chemical properties of a metal are:-

1)The density of metals is usually high.

2)Metals are malleable and ductile.

3)Metals form an alloy with other metals or non – metals.

4)Some metals react with air and corrode. For e.g. Iron.

5)Metals are good conductors of heat and electricity. Lead is an exception.

6)Generally, metals are in a solid state at room temperature. Except for Mercury. Mercury is in a liquid state.

Chemical properties of a non-metal are:-

1)Nonmetals are poor conductors of heat and electricity. Graphite and Gas carbon are exceptions.

2)Unlike metals, nonmetals aren’t malleable and ductile.

3)Nonmetals react more with metals than with nonmetals.

4)Usually, nonmetals react with other nonmetals in high temperature.

5)Most nonmetals do not react with air in room temperature.

White phosphorus is the only nonmetal that reacts with air to form its oxide by burning.

6)Usually, nonmetals do not react with water. Except for Chlorine, chlorine dissolves in water to form an acidic solution.
