Hydrogen bonding and the forming of a snowflake

Water molecules are polar molecules, the electronegative  oxygen with two pairs of lone electrons providing a 'slightly' negative charge that acts with the 'slightly' positive hydrogen atoms to form the incredibly important hydrogen bonds, as illustrated here. It is the dipolarity of water molecules that give rise to the cohesive, adhesive, thermal and solvent properties that you need to learn [Topic 2.2 Water] The video provides a little seasonal focus to the nature of a water molecule and illustrates how its chemical properties give rise to the ...
