WebSep 12, 2024 · The electron’s speed is largest in the first Bohr orbit, for n = 1, which is the orbit closest to the nucleus. The radius of the first Bohr orbit is called the Bohr radius of hydrogen, denoted as a0. Its value is obtained by setting n = 1 in Equation 6.5.6: a0 = 4πϵ0 ℏ2 mee2 = 5.29 × 10 − 11m = 0.529 Å.
