[Extra information: Some properties of metals are given below:
- 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.]
