WebEstimate the radius on the oxygen nucleus. Nuclear radii for different elements Electron diffraction has been used to find the radii of the nuclei of different elements with atomic mass number (or ‘nucleon number’) A. It is found that there is a simple relationship between atomic mass number A and radius r. 3=3/a b c where 3/=1.05×10H&_(. (7)! Web3 jan. 2016 · Two methods are X-ray (or electron or neutron) diffraction and microwave spectroscopy. Explanation: Atomic size is the distance from the nucleus to the edge of the electron cloud. The edge of the electron cloud is not well defined, so chemists use other definitions of atomic size, and they all give slightly different numbers. Metallic radius
