Question

1st excitation energy of h atom is​

Answer 1

The first excitation energy of the hydrogen atom is 10.2 eV.

Answer 2

Answer:

Explanation:

This means to excite hydrogen atom, the energy required to be given to it is E2 – E1 = -3.4 + 13.6 = 10.2 eV. Hence, 10.2 eV is the first excitation energy of the hydrogen atom. Similarly, the II, the III excitation energy of hydrogen atom are E3 – E1, E4 – E1 etc.
