Question

The number of lone pair of electrons in the nitrogen atom in ammonia molecule:​

Answer 1

Explanation:

Ammonia also has four electron pairs and the coordination geometry of nitrogen is based upon a tetrahedral arrangement of electron pairs. There are just three bonded groups, therefore there is one lone pair.

Answer 2

The number of lone pair of electrons in the nitrogen atom in ammonia molecule is one.

• If we see the structure of ammonia molecule it is trigonal pyramidal in shape. The three electrons of Nitrogen atom in the centre are shared by the three Hydrogen atoms. These bonds are covalent in nature.
• The two unshared ones are together referred as a lone pair. Since, there is only one lone pair remaining hence, the number of lone pair of electrons in the nitrogen atom in ammonia molecule is one.
