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 micrometer (symbol: μm) or micrometre (UK & International spelling), also commonly known as a micron, is an SI derived unit of length equaling 1×10−6 of a meter (SI ..more definition+
