315 Covalent Bonding Drawing Lewis Chemistry LibreTextsLewis Beverage cup arrangement for ammonia is portrayed by the valence electrons surrounding the N atom.
The dot dot structure in the case of ammonia reveals that the nitrogen atom joins one pair of electrons with each of the three H atoms, resulting in a complete of a trio shared pairs of electrons.
The NH3 molecule takes a three-sided pyramid-like form because of the arrangement of the outer electrons according to its Lewis dot arrangement.
In the dot symbol depiction of NH3, the N atom is encircled by three dots, each representing a pair of shared electrons with a H atom.
