Question

chemical properties of metal.​

Answer 1

Explanation:

They are usually in the form of a solid at room temperature. They are very good conductors of electricity and heat. Metals are malleable and ductile. They mostly have a very high melting point.

hope it helps you ❤️

Answer 2

• 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.
