  • Chemistry: The Central Science, Chapter 2, Section 3

    A convenient, although non-SI, unit of length used to express atomic dimensions is the angstrom (Å). One angstrom equals 10 –10 m. Thus, atoms have diameters on the order of 1-5 Å. For example, the diameter of a chlorine atom is 200 pm, or 2.0 Å. Both picometers and angstroms are commonly used to express the dimensions of atoms and molecules.
