It must be noted, atoms lack a well-defined outer boundary. The atomic radius of a chemical element is a measure of the distance out to which the … WebThe bond length in MgMg is: 319.7pm. There are several other ways ways to define radius for atoms and ions. Follow the appropriate hyperlinks for literature references and definitions of each type of radius. All values of radii are given in picometres (pm). Conversion factors are: 1 pm = 1 × 10 ‑12 metre (meter) 100 pm = 1 Ångstrom meaning of jauntily
