WebHá 1 hora · The work by Hans M. Kristensen. Matt Korda, Robert Norris, and others in the country-by-country Nuclear Notebooks published in the Bulletin of Atomic Scientists are particularly helpful in understanding limits and uncertainties in such data—and the extent to which many estimates are dated, uncertain, or based on uncertain sources. Web1. Atomic Radius. Atomic radius increases Atomic radius increases. Atomic radius is the distance from the atom’s nucleus to the outer edge of the electron cloud. In general, atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant.
