The electron geometry around an atom with three lone pairs and one single bond is tetrahedral. This is because electron pairs, whether they are bonding pairs or lone pairs, repel each other and arrange themselves as far apart as possible. In this case, four regions of electron density (three lone pairs and one bonding pair) adopt a tetrahedral arrangement to minimize repulsion.
