Determine the radius of the first orbit of the hydrogen atom. What would be the velocity and frequency of the electron in the first orbit? Given: h = 6.62 x 10-34 Js, m = 9.1 x 10-31 kg, e = 1.6 x 10-19 C, k = 9 x 109 N m2 C-2.
The radius of the nth orbit of hydrogen atom is given by
For first orbit, n = 1
= 2.19 x 106 ms-1
