Description of the atomic radius of an atom

WebApr 8, 2024 · It is defined as one half of the distance between the nuclei of the two adjoining metal ions that are joined by a metallic bond. The atomic radius of an atom is measured with the help of X-ray or several other spectroscopy methods. The atomic radii of the elements tend to vary in the periodic table but a fixed manner. WebThe ionic radius is the distance between the nucleus and the electron in the outermost shell of an ion. When an atom loses an electron to form a cation, the lost electron no longer contributes to shielding the other electrons from the charge of the nucleus; consequently, the other electrons are more strongly attracted to the nucleus, and the ...
