  • Models of bonding in atoms and molecules:

  • Single Covalent Bond

  • Double Covalent Bond

  • Triple Covalent Bonds

  • Water our life drink

  • Ball and stick modelsH2O

    NH3H2 ,N2, O2

  • Ionic BondsBall and stick model of NaClNaCl crystal

  • Ionic compounds have charges in them

  • Solutions samples

  • Activity 1Atoms in Ionic compounds are linked by ions:.

  • From abstract to concrete

  • We successfully continued

  • Finding:Physical properties are determined by nature of Chemical bonds

  • ObservationsFindings:Ionic compounds are composed of Ions so they are conductors
