WebSep 12, 2024 · 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. We can substitute a0 in Equation 6.5.6 to express the radius of the n th orbit in terms of a0: rn = a0n2. WebOct 30, 1975 · According to Bohr's theory (1913) of atom the electron moves with velocity v in the circular orbit of radius r. If e is the charge on the electron in esu and c the velocity of light, then e/c is the charge in emu. The current or charge passing a given point per unit time is then ( e / c ) ( v /2π r ).
