To summarize, ammonia is a polar molecule because its electron geometry is trigonal pyramidal and the dipoles of N-H bonds do not cancel out. Remember, the net dipole of the molecule is the vector sum of all the dipoles and here it equals zero because the bonds are equivalent and pointing in opposite directions.
In the ammonia molecule, the three hydrogen atoms attached to the central nitrogen are not arranged in a flat, trigonal planar molecular structure, but rather in a three-dimensional trigonal pyramid (Figure 7.18) with the nitrogen atom at the apex and the three hydrogen atoms forming the base.

Ammonia (NH₃), known for its sharp, distinct odour, is a significant example of a Brønsted–Lowry base. According to Brønsted–Lowry theory, a base is defined as a proton acceptor. Ammonia exemplifies this by accepting a proton (H⁺) and forming an ammonium ion (NH₄⁺).
