Which of the following is the correct representation of ammonium ion?
Which of the following is the correct representation of ammonium ion?
The correct option is D
The nitrogen atom has five valence electrons and hydrogen atom has one valence electron. In ammonia, each of the three hydrogen atoms is bonded to the nitrogen atom by a pair of shared electron. Thus, the nitrogen atom in ammonia is left with a lone pair of electrons. This ammonia molecule combines with a hydrogen ion H+, which has no electrons in its outermost orbit in such a way that the lone pair of electrons on the nitrogen atom is shared by the hydrogen ion. The latter thus acquires the helium configuration. The bond which is formed between the nitrogen atom in ammonia and the hydrogen ion is a coordinate bond and is represented by ‘→’ whereas a covalent bond is represented by ’-’.
Formation of NH4+ ion
