Electron pair Beverage cup structure for NH3 is shown by the valence electrons surrounding the nitrogen atom.
The Lewis dot structure for NH3 exhibits that the nitrogen atom connects 1 pair of e- with each of the three hydrogen atoms, resulting in a total of
three shared pairs of electrons.
The NH3 molecule takes a trigonal pyramidal
structure due to the
placement of the valence electrons according to its Electron pair Beverage cup arrangement.
In the dot symbol representation of ammonia, the nitrogen atom is encircled by three points, each representing a pair of joined electrons with a H atom.
