Question

List the physical and chemical properties oc metals

Answer 1

physical properties:

• Shiny (lustrous) in nature.
• Metal is a good conductor of electricity and heat.
• Density and melting point is high.
• Mouldable (Malleable)
• Ductile.
• At room temperature, it is in solid form except for mercury.
• Opaque.

chemical properties:

• Some metals have multiple oxidation states.
• Metals form cations when ionized, and the reason for this is because metals have a larger radius that offsets the attractive forces of their increasingly positively charged nucleus.
• Metals are structured in a crystal lattice, where the individual atoms of the metal are arranged in a neat grid.
• Metals have a large number of delocalized electrons surrounding them, and this is called an electron sea model.
• The metals in our universe are formed at the core of stars, where nuclear fusion creates increasingly massive element

Answer 2

Metals in pure form have a characteristic metallic lustre.

Metals are generally hard. However, hardness varies from metal to metal.

Metals are generally malleable. This means they can be beaten into thin sheets.

Metals are usually ductile. This means most metals can be drawn into thin wires.
