WebFor any state of hydrogen atom nth Bohr’s state radius is given by using r n = 137 n2˜ e n = 1,2,3,——-λ D is the de Broglie wavelength corresponding to the Bohr’s first orbit. Since first Bohr’s orbit contains one complete de Broglie wavelength. Atomic fine structure constant ‘α’ is given by. λ D = 137λ e α = λ e λ D ≃ 1 ... WebThe radius of the first Bohr orbit of a hydrogen atom is 0.53 × 10 8 cm. The velocity of the electron in the first Bohr orbit is:A. 4.376 × 108 cms 1B. 2.188 × 108 cms 1C. 1.094 × 108 …

WebFeb 20, 2024 · Bohr used the planetary model to develop the first reasonable theory of hydrogen, the simplest atom. Atomic and molecular spectra are quantized, with hydrogen spectrum wavelengths given by the formula 1 λ = R( 1 n2 f − 1 n2 i), where λ is the wavelength of the emitted EM radiation and R is the Rydberg constant, which has the value WebNov 25, 2012 · Suppose an electron was bound to a proton, as in the hydrogen atom, but by the gravitational force rather than by the electric force. What would be the radius of the first Bohr orbit? Homework Equations r = h^2 / 4∏^2*mke^2 The Attempt at a Solution I'm not sure how to manipulate the above equation to account for gravitational force. tandy las vegas
