104 Writing Lewis Structures Chemistry LibreTextsElectron pair Beverage cup arrangement in the case of NH3 is shown by the outer electrons surrounding the N atom.
The dot dot
arrangement for NH3 reveals that the nitrogen atom connects one pair of e- with each of the three H atoms, resulting in a overall of a trio united pairs of electrons.
The NH3 molecule adopts a trigonal pyramidal structure attributed to the placement of the valence electrons according to its Lewis Beverage cup arrangement.
In the
dot dotpoint depiction of NH3, the nitrogen atom is enveloped by three dots, each representing a pair of united electrons with a H atom.
