Chapter 8, Electron Configuration and Chemical Periodicity

The atomic radius of a chemical element is the distance from the center of the nucleus to the outermost shell of an electron. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. Depending on the definition, the term may apply only to isolated atoms, or also to atoms in condensed matter, covalently bound in molecules, or in ionized and excited states; and its value may be obtained through experimental measuremen… WebbUnder most definitions the radii of isolated neutral atoms range between 30 and 300 pm ( trillionths of a meter), or between 0.3 and 3 ångströms.
