Question

Quizplus · Accepted Answer

The molecule NH3 has a tetrahedral electron-pair geometry due to four regions of electron density (three bonds and one lone pair). Its molecular geometry is triangular pyramidal, and the H-N-H bond angle is approximately 109.5 degrees, slightly less due to the lone pair repulsion.
