Is ammonium ion a radical?
The ammonia molecule,
In aqueous solution, this lone pair is conceived to donate to an hydrogen ion in an acid base reaction as shown:
All chemical reactions conserve charge. Has charge been conserved here?
Certainly, we can measure the extent of this equilibrium reaction (conveniently by measuring the
In ammonium cation, there are SIX electrons associated with nitrogen, rather than the 7 required for neutrality. The nitrogen in ammonia is (so-called) quaternized, and thus bears a positive charge. Certainly, we can use ammonium salts such as
