• Metallic Bonding

  • Metallic bonding occurs with negative ions and positive ions, mostly when metals lose most of their electrons to the sea of delocalised electrons, there would be a attraction between positive ions and the sea of delocalised electrons

  • Most of the metals are positive due to the reason of losing most of their electrons to the sea of delocalised electrons, this usually occurs as metals have electropositivity within them

• Physical Properties Of Metallic Bonding

  • Most of the metals have really high boiling and melting point as really high energy is needed to overcome the strong force of the attraction of positive ions to the sea of delocalised electrons, thus really high energy is needed

    
    

  • Metals have really good electric conductivity, metals can conduct electricity as they can pass through them and carry electrons

  • Metals can easily be bend and shaped, this is called malleable, metals can also be structured to wire form, this process is known as ductile

• Summary For Chapter 3

  • There is a difference between chemical compounds, elements and mixture

  • A covalent bond is a bond by 2 atoms sharing their outer electrons, this particular bonding can be illustrated by dot-cross diagram

  • Covalent bonding share a lot of electrons requires a more complex molecules and multiple bonds

  • A ionic bond is a strong electrostatic attraction or a bond between two oppositely charged atoms, cations and anions

  • Dot-Cross diagrams are used to describe the formation of ionic bonds of metal and non metallic elements
