WebThe 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, … WebPeriodicity in atomic radius and ionic radius For normal elements (a) In a period from left to right effective nuclear charge increases because the next electron fills in the same shell. So the atomic size decreases. For example the covalent radii of second period elements in A° are as follows − Li Be B C N O F 1.23 0.89 0.80 0.77 0.74 0.73 0.72 pop cycle tucson hours
