As per bohr theory difference between successive energy levels in the hydrogen atom: 1)increases
2)decreases
3)remains constant
4)has no definite order as 'n' value increases​

decreases

Explanation:

Decreases

Explanation:

The value if energy level can be calculated by E1/n^2

So as the levels increase the energy decreases and hence the difference too

Bohr's model of the atom was both a success and a failure. It successfully predicted the frequencies of the lines in the hydrogen spectrum, so it seemed to be valid. Nevertheless the model was a total failure when it tried to predict energy levels for atoms with more than one electron.

Explanation:

➺ The great success of the Bohr model had been in explaining the spectra of hydrogen-like atoms;i.e., ions with a single electron around a positive nucleus. The Schroedinger equation replicated this explanation in a more sophisticated manner and the Bohr analysis was considered obsolete. ... See Relativistic Bohr Model.
