Answer 2

Properties of Metals:

Physical Properties of Metals:

• Metals  can be hammered into thin sheet. It means they possess the property of malleability.
• Metals are ductile. They can be drawn into wires.
• Metals are good conductors of heat and electricity.
• Metals are lustrous which means they have a shinny appearance.
• Metals have high tensile strength .It means they can hold heavy weights.
• Metals are sonorous .It means when we strike them, they make a ringing sound.
• Metals are hard .It means they cannot be cut easily.

Chemical Properties:

• Reaction with oxygen- Metals react with oxygen and form metallic oxides which are basic in nature.
• Aqueous solution of metal oxide turns red litmus paper into blue.
• Reaction with water- Metals react with water, metal hydroxide and hydrogen gas is formed.
• Reaction with acid: Metals react with acids and form salt and hydrogen gas. Some metals vigorously react with acids.
• Reaction with bases: Metals react with bases such as sodium hydroxide and forms salt and hydrogen gas.
• Displacement reaction: A more reactive metal displaces a less reactive metal from its salt solution. These types of reaction are called displacement reaction.
