Answer 2

Explanation:

✦ 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.

✦ Not all metals react with water. However, highly reactive metals like sodium and potassium react with water violently and an exothermic reaction takes places where the hydrogen immediately catches fire.

✦ Salt and hydrogen are produced when a metal reacts with an acid.

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