} As a result, there are no lone pairs of electrons, but bonding pairs of electrons also repel each other. The electron geometry is tetrahedral with a bond angle {eq}\rm = 109.5^o Solution First of all, let’s start with the basics. NH3 electron geometry is: ‘Tetrahedral,’ as it has four group of electrons. Methane has a tetrahedral structure with Carbon at the center and Hydrogen atoms at the four vertices.
