WebThe CODATA value for the Bohr radius is based on the formula a0 = ℏ/αmec, where: a 0 is the Bohr radius. ℏ is the reduced Planck constant. α is the fine-structure constant. m e is the mass of an electron. c is the speed of light in a vacuum. The Bohr radius is derived from the Bohr model of the atom. WebIn Bohr’s model, radius a n of the orbit n is given by the formula a n = h 2 n 2 ε 0 /π 2, where ε 0 is the electric constant. As Bohr had noticed, the radius of the n = 1 orbit is approximately the same size as an atom. …

WebApr 13, 2024 · Bohr's Radius: If 'e,' 'm,' and 'v' be the charge, mass, and velocity of the electron respectively, 'r' be the radius of the orbit, and Z be the atomic number, the equation for the radii of the permitted orbits is given by r = n 2 xr 1 , where 'n' is the principal quantum number, and r 1 is the least allowed radius for a hydrogen atom, known as ... WebSolving this for the radius of the nth orbit gives: r n = [h 2 /4p 2 mkZe 2] n 2. r n = [5.29 x 10-11 m] n 2. 5.29 x 10-11 m is known as the Bohr radius. So, Bohr's assumption that the angular momentum is quantized produces the result that the radii of the electron's allowed orbits are also quantized.
