With the sulfur(IV) fluoride SF 4 molecule, electron pairs are based on a trigonal bipyramid geometry. Two of the fluorine atoms and the lone pair are in a trigonal planar arrangement - all the F-S-F angles are 102 o except the one described below.
4), the sulfate ion (SO 2− 4), the phosphate ion (PO 3− 4). Thiazyl trifluoride (SNF 3) is tetrahedral, featuring a sulfur-to-nitrogen triple bond. Other molecules have a tetrahedral arrangement of electron pairs around a central atom; for example ammonia (NH 3) with the nitrogen atom surrounded by three hydrogens and one lone pair.

Hence the molecule has three electron pairs and is trigonal planar for electron pair geometry. The one lone electron exerts a less repulsion than normal on the two bonding oxygen atoms so they are able to spread out more to a 134 o bond angle from the ideal of 120 o. The Lewis diagram is as follows: N = 5 e-

The d 8 system, Au(III) is stable as the electron from the d x 2-y 2 is removed. Mostly it prefers square planar geometry and more stable than both Au(II) and Au(I). The d 10 system, Au(I) favors mostly linear geometry with coordination number = 2. Why do the d 9 systems usually not undergo complete distortion to square planar geometry?
2. Determine from the Lewis Dot structure the number of electron pairs around the central atom - bonding and non bonding pairs. In the case of a multiple bond - count it as one pair. 3. Determine the arrangement of the electron pairs to the central atom. 4. Obtain the molecular geometry from the direction of the bonding pairs for that arrangement.

Electron Geometry. You may come across questions asking for the electron geometry as opposed to the molecular geometry. In electron geometry, both bonds and lone pairs are considered the same. In other words, any molecule with 4 groups of something, be it 3 bonds and 1 lone pair or 2 bonds and 2 lone pairs, will have the same electron geometry.
