Bonding In Chemistry

1. solid
2. liquid
3. gaz

Nota:

• Depend on polarity

1. Van Der Waal forces
   1. London dispersion

      Nota:

      • Between 2 non-polar molecules
   2. Dipole-Dipole dispersion

      Nota:

      • Attraction between permanent and non-permanent dipoles
   3. Dipole-induced attraction

      Nota:

      • Attraction between permanent and non-permanent dipoles
2. H-bonds

   Nota:

   • Between Hidrogen and other atoms in a molecule

1. Ionic

   Nota:

   • ·Always metal and non-metal ·Giving of electrons
2. Covalent

   Nota:

   • ·Sharing of one or more pairs of electrons between 2 or more bonding atoms
3. Metalic

   Nota:

   • ·Made of metals ·They loose electrons when neutral ·Electrons lost are délocalised ·Strenght depends on: -nº of délocalised e -charge of cation -radius of cation
