Tetrahedral Electronic Geometry: AB 3 U Species (One Lone Pair of Electrons on A)

Tetrahedral Electronic Geometry: AB 3 U Species (One Lone Pair of Electrons on A). Some examples of molecules with this geometry are: NH 3 , NF 3 , PH 3 , PCl 3 , AsH 3 These molecules are our first examples of central atoms with lone pairs of electrons.
