Octahedral geometry electron

When there are six electron groups around the central atom, it is sp d hybridized. AB molecules and ions with no lone pairs on the central atom have octahedral electronic geometry, octahedral molecular geometry and sp d hybridization on the central atom. 

The electron configuration expected for Ni2+ is [Ar]3unpaired electrons it would have to be (c) square planar in its electronic geometry, as both the octahedral and tetrahedral geometries require a species to have two unpaired electrons. Square planar does not. 

This polyatomic ion (type AB6), like (c), does not obey the octet rule without modification since 12 electrons must be shared to form 6 Sb-F bonds. Sb is a 5 A element, but the charge on the ion gives an extra electron which participates in bonding. The Lewis formula predicts 6 electron groups around the central Sb atom and an octahedral electronic geometry. There are no lone pairs on the Sb atom, so the ionic geometry is the same as the electronic geometry (Section 8-12). 

The Lewis formula shows 6 electron groups around the central P atom. The electronic geometry and the ionic geometry are both octahedral because there are no lone pairs of electrons on P (Section 8-12). 

The Lewis formula predicts 6 electron groups around the central Xe atom and its electronic geometry is octahedral. The molecular geometry is square planar due to the presence of 2 lone pairs of electrons on the central Xe atom. 

Angular overlap calculations of the energies expeeted for different numbers of d electrons and different geometries can give us some indication of relative stabilities. Here, we will eonsider the three major geometries, octahedral, square planar, and tetrahedral. In Chapter 12, similar calculations will be used to help describe reaetions at the coordination sites. 

By similar reasoning, VSEPR theory predicts octahedral electronic geometry and octahedral molecular geometry for the PFg ion, which has six valence shell electron pairs and six F atoms surrounding one P atom.

If the Lewis formula for a molecule or ion shows only one lone pair In Unear, trigonal planar, tetrahedral, or octahedral electronic geometry, all positions are equivalent, so it doesn t matter where we place the lone pair. In trigonal bipyramidal electronic geometry, place the lone pair in the equatorial position where it is least crowded, and put the bonded atoms in the other positions.

Octahedral A term used to describe the electronic geometry around a central atom that has six regions of high electron density. Also used to describe the molecular geometry of a molecule or polyatomic ion that has one atom in the center bonded to six atoms at the corners of an octahedron (ABg).

E17.17 Iodine is the central atom in IPs- Five unpaired electrons form bonds with five fluorine atoms, plus one lone electron, giving a total of six electron pairs. Therefore, the electronic geometry is octahedral with one position occupied by a lone pair giving a square pyramidal arrangement of atoms.
