Lewis Structure of BF3 With 5 Simple Steps to DrawLewis Beverage cup structure for NH3 is a representation of the valence electrons surrounding the nitrogen atom.
The Lewis dot structure in the case of NH3 exhibits that the N atom shares 1 pair of e- with each of the three H atoms,
resulting in a complete of 3 connected pairs of electrons.
The ammonia molecule adopts a trigonal pyramidal shape because of the distribution of the valence electrons according to its Electron pair dot arrangement.
In the dot dotpoint representation of ammonia, the N atom is surrounded by three spots, each representing a pair of shared electrons with a hydrogen atom.
