The picometer (symbol: pm) or picometre (International spelling) is a unit of length in the metric system, equal to 1×10−12 m, or one trillionth (1/1000000000 ..more definition+
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.
