Water droplets are made up of molecules of water, which is a compound composed of two hydrogen atoms and one oxygen atom (H2O). Each water molecule is made up of two hydrogen atoms bonded to one oxygen atom. The oxygen atom is slightly more electronegative than the hydrogen atoms, meaning it attracts electrons more strongly. This creates an asymmetrical distribution of charge within the molecule, with a slight positive charge near the hydrogen atoms and a slight negative charge near the oxygen atom. This causes water molecules to be polar, meaning they have a positive end and a negative end. The polar nature of water molecules allows them to form bonds with each other through hydrogen bonding. Hydrogen bonding occurs when the positive hydrogen end of one water molecule forms a bond with the negative oxygen end of another water molecule. These hydrogen bonds are responsible for the unique properties of water, such as its high surface tension and high specific heat capacity.
