Hybridization and Steric Number Concepts

This video tutorial explains how to calculate the steric number, which is the sum of sigma bonds and lone pairs around an atom. It discusses how the steric number helps determine the hybridization of an atom, providing general rules and examples with molecules like methane, ammonia, carbon monoxide, and alkyl halides. The video also offers additional resources through a Patreon membership.
