Answer 1

Hola!

The properties of metals are -

◆ Physical properties -

• Metals are generally shiny. This property is called lustre.
• Metals are generally hard to cut or break.
• Metlas can be beaten into thin sheets. This property is called malleability.
• Metals can be drawn into thin sheets. This property is called ductility.
• Metals conduct electricity.
• Metals conduct heat.
• Metals are generally sonorous.
• Metals are available in the form of solid, except Mercury.

◆ Chemical properties -

• Metal + Oxygen ==> Metal oxide.
• Metal + Water ==> Metal Hydroxide + Hydrogen.
• Metal oxide + Water ==> Metal Hydroxide.
• Metal + Dilute acid ==> Salt + Hydrogen.
• Metal A + Salt solution of B ==> Salt solution of A + Metal B.

PROPERTIES

KEY PHYSICAL PROPERTIES

• Metals are lustrous, and this is because of incident radiation causing electron exciation. As the electrons fall back to their original energy state, they emit photons causing the metals to shine. This is foundation of the pholoelectric effect.
• Metals are malleable and ductile, meaning that can be drawn into long wires and pounded in sheets. This is why metals are so useful in construction.

• Metals are generally have very high melting points, and this is because of the atomic structure of metals (that is more of a chemical property).

• Metals are generally have low heat capacities, melting that they don't retain heat very well. This is why most metals are thermally conductive rather than being thermal insulators.

KEY CHEMICAL PROPERTIES

• Some metals have multiple oxidation states. For example, chromium (Cr) has a +1,+2,+3,+4,+5 and +6 oxidation state. This wide range of oxidation states make metals very versatile reactants. There are exception: silver (Ag) only has +1 oxidation state and zinc(Zn) only has +2 oxidation state.

• Metals are structured in a crystal lattice, where the individual atoms of the metal are arranged in a neat grid. This contributes to their uniforms geometry, and why metals can be made retain certain shapes. This also explain why metals have such a high melting point.

• Metals have a large number of delocalized electrons surrounding them and this is called an electron sea model. These delocalized electrons contribute to the electrical and thermal conductivity of metals.

• The metals in our surrounding are formed at the core of stars , where nuclear fision creates increasingly massive elements.
