# What is the steric number of the central atom in carbon disulfide?

The steric number of the central atom in $C {S}_{2}$ is $\text{2}$.
And given, $S = C = S$, in which the carbon atom has no lone pairs, the steric number is 2. The parameter is sometimes useful for $\text{VESPER}$ determinations in which the number of electron pairs about the central atom, bonding AND non-bonding, determines molecular geometry.
