sir ,i have tried to find the velocity of electron in the valence shell of hydrogen by equating the electrostatic force between electron and protons with the formula mv^2/r where m is the mass of electron and r is the atomic radius .is this method correct or not?if not ,then suggest other method to find the velocity of electron in a shell.
