Géométrie et schéma de Lewis
Electron pair Beverage cup structure in the case of NH3 is a representation of the valence electrons surrounding the N atom. The dot point arrangement in the case of NH3 exhibits that the nitrogen atom connects one pair of electrons with each of the three H atoms, resulting in a complete of 3 joined pairs of electrons. The ammonia molecule adopts a trigonal pyramidal form due to the placement of the valence electrons according to its Electron pair Beverage cup arrangement. In the Lewis symbol depiction of NH3, the N atom is encircled by three dots, each representing a pair of joined electrons with a hydrogen atom.
