http://www.astronoo.com/en/articles/size-of-atoms.html The atomic radius of a chemical element is a measure of the size of its atom, usually the mean or typical distance from the center of the nucleus to the outermost isolated electron. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. Four widely used … Visa mer In 1920, shortly after it had become possible to determine the sizes of atoms using X-ray crystallography, it was suggested that all atoms of the same element have the same radii. However, in 1923, when more … Visa mer The way the atomic radius varies with increasing atomic number can be explained by the arrangement of electrons in shells of fixed capacity.
