About Bohr radius
The Bohr radius is a unit of length in atomic units. The Bohr radius expresses the most likely position of the electron in a hydrogen atom, the simplest atom, in its ground state (the Bohr model of an atom).
The Bohr radius unit is named after the Danish physicist Niels Henrik David Bohr (1885 - 1962), who made fundamental contributions to understanding the atomic structure and quantum mechanics.
The Bohr radius of hydrogen has a value of approximately 5.3 × 10-11 meters (a0 ≈ 5.3 × 10-11 m), the base unit of length in the International System of Units (SI).
The Bohr radius (a0) is also equal to approximately 0.53 angstroms (Å) (a non-SI unit of length), or 5.3 × 10-5 micrometers (μm), or 5.3 × 10-8 millimeters (mm) or 5.3 × 10-9 centimeters (cm), which are SI units of length.
The Bohr radius is used in atomic physics calculations.
