The steric number of a molecule is the number of atoms bonded to the central atom of a molecule (σ sigma bond) plus the number of lone pairs on the central atom. It is often used in VSEPR theory (valence shell electron-pair repulsion) in order to determine the particular shape, or molecular geometry, that will be formed.

The steric number of a molecule is a tool used to illustrate a molecule's shape or geometric representation. The grading system for the numbers relates the different geometric shapes. For example, if the steric number is 1 then the geometry of the molecule is linear. The steric number is calculated by using the electrons of the central atom, or the atom around which the other atoms rotate, and the number of bonds of those rotating atoms.

Steric number in VSEPR. Calculating the steric number of a molecule's central atom is a vital step in predicting its geometry by VSEPR theory. On the molecule SF4, for example, the central sulfur atom has four ligands about it, calculated by considering sulfur's coordination number.

This applies both to bonding electrons as well as lone pairs. In order to use the VSEPR principle, one needs to compute a number known as the steric number. This is given by. The second number can be determined directly from the Lewis structure. Once the steric number is known, the basic shape of the molecule is given by the following assignment of shapes: The basic shapes are shown in the left column of the figure below: Figure 7: VSEPR shapes.

Steric number in VSEPR Calculating the steric number of a molecule's central atom is a vital step in predicting its geometry by VSEPR theory. On the molecule SF 4, for example, the central sulfur atom has four ligands about it, calculated by considering sulfur's coordination number. In addition to the four ligands, sulfur also has one remaining lone pair. Thus, the steric number is 5.
