electron arragement

is the electron arrangement the same as the molecules's geometry name?

[Holiday Parsons 2D]

the electron arrangement can differ from the molecular geometry. Molecular geometry refers to the arrangement of bonds. Electron geometry is determined by the number of bonds and lone pairs and is the arrangement of electron groups. For example, the electron domain geometry for NH3 is tetrahedral. But the molecular geometry for NH3 is trigonal pyramidal.

[Azlyn Hernandez 2E]

No, the electron arrangement and the molecular geometry name are not necessarily the same. The electron arrangement refers to the distribution of electrons around the central atom, including both bonding and non-bonding pairs. Molecular geometry, describes the arrangement of only the atoms, ignoring the lone pairs.
