VSEPR, Polarity, and Hybridization, Top Exam Questions and answers, 100% Accurate. Verified. VSEPR Theory - --A theory that predicts some molecular shapes based on the idea that pairs of valence electrons surrounding an atom repel each other -states that repulsion between the sets of valence-level electrons surrounding an atom causes these sets to be oriented as far apart as possible Hybridization - -The mixing of two or more atomic orbitals of the same atom to produce new orbitals; hy...
