CHEMICAL BONDS (IONIC BOND (formed between atoms of metal elements that…

- - - - 1.Electron arrangement of both atom of metal and non-metal
      - Metal atom release electrons to achieve stable octet electron arrangement
      - Positive metal ion is formed
      - Non-metal atom receive electrons to achieve stable octet electron arrangement
      - Negative non-metal ion is formed
      - Positive ion and negative ion is attracted by strong electrostatic forces
      - Ionic compound is formed
    - - Insoluble in organic solvent
      - Can conduct electricity in molten or aqueous state
      - Soluble in water
      - High melting and boiling point
      - Have Strong Electrostatic forces between ions
    - - Potassium Iodide, KI
      - Barium Oxide. Bao
      - Magnesium Oxide, MgO
      - Copper Oxide, CuO
      - Sodium Chloride ,NaCl
- - - - Atom x need to contribute electron to achieve stable octet electron arrangement.
      - Atom y share electron with atom x to form single/ double / triple colavent bond
      - Atom y need to contribute electron to achieve stable octet electron arrangement.
      - so, covalent compound is formed
      - 1.Electron arrangement of both atoms
    - - Soluble in organic solvent
      - Cannot conduct electricity in any state
      - Insoluble in water
      - low melting and boiling point
      - Have Weak Van der Waals forces(intermolecular forces between molecule)
    - - Water, H2O
      - Hydrogen , H2
      - Carbon Dioxide, CO2
      - Oxygen, O2
      - Methane, CH4
