Since the motions of the atoms in a molecule are determined by quantum mechanics, "motion" must be defined in a quantum mechanical way. The overall (external) q… See more

Molecules, by definition, are most often held together with covalent bonds involving single, … See more

Isomersare types of molecules that share a chemical formula but have difference geometries, resulting in different properties: 1. A puresubstance is composed of only one type of … See more

A bond angle is the geometric angle between two adjacent bonds. Some common shapes of simple molecules include: 1. Linear: In a linear model, atoms are connec… See more

Line or stick– atomic nuclei are not represented, just the bonds as sticks or lines. As in 2D molecular structures of this type, atoms are implied at each vertex. See more
