Bond Strength

Bond Strength

Bond Strength. Bond length (the distance between the nuclei of atoms in a covalent bond) decreases with the addition of more shared pairs = stronger bond Recall: What is “ionization energy”? Similarly, energy is required to break a bond between atoms in a molecule: bond dissociation energy .

Control of Structure

Control of Structure

Control of Structure. Why do elements and compounds adopt one structure as opposed to another?. Thermodynamics Review: G = H - TS. Bond Strength Favored by strong bonds. Freedom of Movement Favored by more particles. Temperature Control?. Thermodynamics Review: G = H - TS.
