In
AXE method for VSEPR theory
states that the classification is AX3E1.
Trigonal pyramidal geometry in ammonia
The
nitrogen inversion.[1]
-
The electron pair arrangement of ammonia is tetrahedral: the two lone electrons are shown in yellow, the hydrogen atoms in white -
The molecular geometry can be inferred from the electron pair arrangement, showing that ammonia has trigonal pyramidal geometry.
