Structure of water
Water (H2O) consists of two hydrogen atoms
covalently bonded to one oxygen atom. +
Each hydrogen shares a pair of
electrons with the oxygen. The oxygen
has a greater affinity for electrons than 104.5 °
the hydrogens, so it `pulls' the
electrons closer. +
This makes the oxygen slightly negative (indicated by )
and the hydrogens slightly positive (indicated by +).
This creates different charged regions, making water a polar
molecule. Because it has two charged regions it is dipolar.
