METALS AND NON- METALS, REACTION OF METALS WITH OXYGEN, Reaction Of Metal…

- - - - Malleable, i.e., can be beaten into thin sheets
      - Ductile, i.e., can be drawn into thin wires
      - Solids at room temperature, except mercury, which is liquid at room temperature.
      - Metals produce ringing sound when struck hard by rigid things. They are called sonorous
      - Hard and have a high tensile strength
      - Generally metals have high melting and boiling point
      - Metals have high density.
      - Metals have shiny surface
  - - - Metals like sodium, potassium, lithium and calcium react vigorously with dilute HCl and H2SO4 to form their metal salt and hydrogen gas.
        Metals which fall below hydrogen in the reactivity series does not react with dilute acids.
      - When more reactive metal react with solution of less reactive metal salt, more reactive metal displace less reactive metal from its salt and forms hydrogen gas, such a reaction is known as displacement reaction.
      - Some metals react with water to form metal hydroxide and hydrogen gas
        Some metals like copper, gold, silver and platinum do not react with water
      - Metals react with oxygen to form metal oxides
        Metal oxides are basic in nature
- - - - They do not react with water to evolve hydrogen gas.
      - Generally, Non-metals do not react with acids.
      - Metal reacts with oxygen to form non- metallic oxides which are basic in nature
      - Some non-metals react with bases to form complex reactions
  - - - Non-metals are not malleable
      - Non-metals are not sonorous
      - Almost all non-metals are brittle and soft
      - Non-metals are found in all three states
      - Non-metals are not ductile
      - Generally, non-metals have low melting and boiling point.
      - Most non-metals have low densities
      - Most non-metals have a dull texture
