Answer:
The formation of the ammonium ion is an example of coordinate bonding.
Explanation:
To get a better understanding of how the ammonium ion,
NH
+
4
, is formed, start with the Lewis structure of ammonia.
The molecule has a total of 8 valence electrons, 5 from nitrogen and 1 from each of the three hydrogen atoms.
The nitogen atom will bond with the hydrogen atoms via single bonds. Notice that you have a lone pair of electrons present on the nitrogen atom.
Now, a hydrogen ion,
H
+
, which essentially is a proton, will be attracted to that lone pairs of electrons. The bond that is formed when a hydrogen ion is attached to the ammonia molecule is called a coordinate bond (or a dative covalent bond).
