Question

if energy of first excited state of hydrogen atom is -x unit. calculate second excitation energy of hydrogen atom​

Answer 1

Explanation:

Thus, in a hydrogen atom (composed of an orbiting electron bound to a nucleus of one proton), an excitation energy of 10.2 electron volts is required to promote the electron from its ground state to the first excited state. A different excitation energy (12.1 electron volts) is needed to raise the electron from its ground state to the second excited state.
