The repulsion between valence electron pairs in the outer shell of the central atom determines the shape of the molecule. You must determine the steric number (SN) — the number of bonding pairs and lone pairs about the central atom.

WebJan 1, 2014 · There are three basic steps to determining the molecular shape of a molecule: Write the Lewis dot structure of the molecule. That gives you the steric number (SN) — the number of bond pairs and lone … WebOct 31, 2024 · Subtract the number of actual valence electrons in the molecule from the number of lewis electrons to find the number of bonds in the final structure. In the example of water, the number of lewis electrons is 12 (2 electrons from each Hydrogen atom (follows duet rule) plus 8 electrons from the oxygen atom (follows octet rule)).
WebIn terms of the geometry of the molecule. So the geometry of the electron clouds are attempting to be, once again, a tetrahedral fashion, but the geometry of the molecule is different because you ignore lone pairs of electrons. And so when you look at the shape, if you look at the shape of this-- I'll go ahead and draw the shape over here.
