The Bohr radius (a0) is a physical constant, approximately equal to the most probable distance between the nucleus and the electron in a hydrogen atom in its ground state. It is named after Niels Bohr, due to its role in the Bohr model of an atom. Its value is 5.29177210903(80)×10 m. 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 … See more 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 … See more • Atomic radii of the elements (data page) • Chemical bond • Covalent radius • Bond length • Steric hindrance See more Widely used definitions of atomic radius include: • Van der Waals radius: In the simplest definition, half the minimum distance between the nuclei … See more The way the atomic radius varies with increasing atomic number can be explained by the arrangement of electrons in shells of fixed capacity. … See more • Difference between empirical and calculated data: Empirical data means "originating in or based on observation or experience" or "relying on experience or observation alone often without due regard for system and theory data".
