Answer Details
The bond formed when ammonia reacts with hydrogen ion to form ammonium ion is a dative bond. In this reaction, the lone pair of electrons on the nitrogen atom of the ammonia molecule is donated to the hydrogen ion (H+) to form the ammonium ion (NH4+). This type of bond is also called a coordinate covalent bond, as both electrons in the bond come from the same atom (in this case, the nitrogen atom of the ammonia molecule).
