Bohr's radius in hydrogen atom
WebWe went over the Bohr model of the hydrogen atom, which has one proton in its nucleus, so here's the positive charge in the nucleus, and a negatively charged electron orbiting the nucleus. And even though this is not reality, the Bohr model is not exactly what's happening, it is a useful model to think about. ... And so we sketch in the radius ... WebThe slight discrepency with the experimental value for hydrogen (109,677) is due to the flnite proton mass. This will be corrected later. The Bohr model can be readily extended …

WebThe 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 6.38: a0 = 4πε0 ℏ2 mee2 = 5.29 × 10−11m = 0.529Å. 6.39.
