How many times does the electron go around first orbit h atom

1.	How many times does the electron go around first orbit h atom
Answer» The frequency of ELECTRON is given by, V = v2πr v = v2πr where, vis the VELOCITY with which the ELECTRONS are moving and, r is the radiusof the hydrogen atom. Velocity, v = 2.2 ×× 106 m/s radius of the orbit, r = 0.5287 ×× 10-10 m ∴ ∴ f = 2.2×1062×3.14×0.5287×10−102.2×1062×3.14×0.5287×10-10 = 6.6 ×× 1015 HZ
