The Bohr radius (a0 or rBohr) is a physical constant, approximately equal to the most probable distance between the proton and 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 5.2917721067×10^−11 m.
A metric foot (defined as 300 mm, or about 11.8 inches) has been used occasionally in the UK but has never been an official unit. The sizes of the studios at BBC Televi ..more definition+
