Radius of atoms
WebMetallic radius Van der Waals radius v t e The van der Waals radius, rw, of an atom is the radius of an imaginary hard sphere representing the distance of closest approach for another atom. WebThe 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 5.291 772 109 03(80) × 10−11 m. [1] [2] Definition and value [ edit]
