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.
The line (abbreviated L or l) was a small English unit of length, variously reckoned as 1/10, 1/12, 1/16, or 1/40 of an inch. It was not included among the units authoriz ..more definition+
