1. Lewis Structure: Draw the Lewis structure of CS₂. Carbon has four valence electrons, and each sulfur atom has six.
```
S = C = S
```
2. Electron Domains: Count the electron domains around the central atom. An electron domain is a lone pair or a bond. Carbon has two double bonds to sulfur, making a total of two electron domains.
3. Hybridization: The hybridization of an atom is determined by the number of electron domains.
* Two electron domains correspond to sp hybridization.
Therefore, the hybridization of the central carbon atom in CS₂ is sp.
