Answer 1

Answer:

• The density of metals is usually high.

• Metals are malleable and ductile.
• Metals form an alloy with other metals or non – metals.

• Some metals react with air and corrode. For e.g. Iron.
• Metals are good conductors of heat and electricity. Lead is an exception.

• Generally, metals are in a solid state at room temperature. Except for Mercury. Mercury is in a liquid state.
• Many metals produce metal oxide by burning in the oxygen of the air. Highly reactive metals react violently when they’re burnt in oxygen.

• Metals like sodium and potassium are stored in oil as they react with air in seconds. They’re highly reactive metals.
• Less reactive metals like gold, silver, platinum, etc do not tarnish easily. They stay shiny and lustrous.
• Metals produce metal oxide and hydrogen gas while reacting with water.
• Soluble metal oxides dissolve in water and create metal hydroxide.

Generally, a metal displaces a less reactive metal in a metal salt solution.
