Covalent bond: A shared pair of electrons. There is an electrostatic force of attraction between the bonding pairs of electrons and the nuclei of the atoms at each side.
Covalent bonding:
Dispersion forces: exists between all molecules and arises due to very weak electrostatic attraction between induces and temporary dipoles. e.g. Random motion of electrons creates areas in a molecule that are slightly negative and slightly charged.
always say relative e.g. water is relatively high considering it is a small molecule
Ice is less dense than water due to hydrogen bonding
Lewis Diagrams:
H_2 has a simple diagram of H-H. There is a single bond between the two because the valency is 1
What makes nitrogen very inert?
Nitrogen gas bonds in triple bonds. Therefore, to make nitrogen do anything, you need to break a relatively strong triple bond.
NOTE: Pyramidal bond angle is 107 degrees, Triangular planar is 120 degrees. RESEARCH OCTET EXPANSION
