Question
In a molecule of NH4+, how many lone pairs are the on the nitrogen atom?(Remember that one lone pair = two electrons). Group of answer choices3120
Solution
To determine the number of lone pairs on the nitrogen atom in a molecule of NH4+, we need to consider the valence electrons of nitrogen and the charge of the molecule.
- Nitrogen (N) has 5 valence electrons in its outer shell.
- The molecule has a charge of +1. This means there is one less electron in the molecule.
- Nitrogen forms 4 bonds with hydrogen atoms in NH4+, using 4 of its valence electrons.
Subtracting the number of electrons used in bonding from the total number of valence electrons:
5 (from N) - 1 (from the charge of the molecule) - 4 (used in bonding with H) = 0
Therefore, there are no lone pairs on the nitrogen atom in a molecule of NH4+.
