Lewis
Beverage cup arrangement for NH3 is a representation of the valence electrons surrounding the N atom.
The dot point structure for NH3 exhibits that the N atom shares one pair of electrons with each of the three hydrogen atoms, resulting in a overall of three joined pairs of electrons.
The ammonia molecule takes a trigonal pyramidal shape due to the distribution of the valence electrons according to its Lewis dot structure.
In the Lewis symbol depiction of NH3, the nitrogen atom is encircled by three points, each representing a pair of joined electrons with
a H atom.
