An electron in the n = 2 state of hydrogen remains there on the average of about 10 s, before making a transition to n = 1 state. the uncertainty in the energy
An electron in the n = 2 state of hydrogen remains there on the average of about 10 s, before making a transition to n = 1 state. The uncertainty in the energy of n = 2 state is (1) 4-14x 10 eV (2) 4-14x 10 eV (3) 4 14x 10 eV (4) 2:07x 10 eV
