Bohr's velocity formula
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 … WebIf you rearrange Bohr's angular momentum equation to solve for the velocity: v = nh/2pmr and then plug that into the equation: mv 2 = kZe 2 /r you get: mn 2 h 2 /4p 2 m 2 r 2 = kZe 2 /r Solving 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.
