An electron in the hydrogen atom initially in the fourth excited state makes a transition to n ^ th energy state by emitting a photon of energy 2.86 eV. The integer value of n will be ____.
Correct answer
0
Step-by-step solution
E =13.6 ( 1 n ₁^2 - 1 n ₁^2 ) 2.86=13.6 ( 1 n ^2 - 1 5^2 ) aligned & 1 n ^2 =0.21+ 1 2.5 & n ^2=4 & n =2 aligned
