Bonding Pair: This is a pair of electrons shared between two atoms, forming a covalent bond.
VSEPR Theory: The Valence Shell Electron Pair Repulsion theory predicts the shape of individual molecules based on the extent of electron-pair electrostatic repulsion.
A measure of how strongly an atom can attract a bonding pair; it often determines whether the pair remains shared (bonding) or becomes unshared (lone).
