A quick explanation of the molecular geometry of NH4+ including a description of the NH4+ bond angles.
Looking at the NH4+ Lewis structure we can see that there are four Hydrogen (H) atoms attached to the central Nitrogen (N) atom and that there are no lone pair of electrons (on the central N). Based on VSEPR Theory (Valence Shell Electron Pair Repulsion Theory) the electron clouds on the atoms around the N will repel each other. As a result they will be pushed apart giving the NH4+ molecule a tetrahedral molecular geometry or shape.
The NH4+ bond angle will be about 109 degrees since it has a tetrahedral molecular geometry.
