Calculate and draw the number shared electrons NH3
Ammonia (NH3) has a nitrogen atom and three hydrogen atoms. The nitrogen atom has five valence electrons, and each hydrogen atom has one valence electron.
To determine the number of shared electrons in NH3, we need to consider the Lewis dot structure. The Lewis dot structure of NH3 is as follows:
H H

N

H
In this structure, each hydrogen atom shares one electron with the nitrogen atom, resulting in three shared electrons. The nitrogen atom also has a lone pair of electrons that are not shared with any other atom.
So, the number of shared electrons in NH3 is 3.
