A quick explanation of the
A quick explanation of the molecular geometry of H2O including a description of the H2O bond angles. Note. the precise bond angle is 104.5.
Looking at the H2O Lewis structure we can see that there are two atoms attached to the central Oxygen (O) atom and that there are two pair of lone pair of electrons (on the central O). Based on VSEPR Theory (Valence Shell Electron Pair Repulsion Theory) the electron clouds and lone pair electron around the O will repel each other. As a result they will be pushed apart giving the H2O molecule a bent molecular geometry or shape.
The H2O bond angle will be about 109.5 degrees since it has a bent molecular geometry.
