- VSEPR Theory: Valence Shell Electron Pair Repulsion theory predicts the shape of individual molecules based on the concept that electron pairs surrounding an atom tend to repel each other.
- Bond Angle: The angle formed between three atoms across at least two bonds.
- Tetrahedral Geometry: A type of molecular geometry where a central atom is bonded to four other atoms or groups, forming a shape similar to a pyramid with triangular faces.
