Assertion (A) : Hydrogen has only one electron in its 1s orbital but it produces several spectral lines.
Reason (R) : There are many excited energy levels available in H atoms.

(A) : Hydrogen has only one electron in its orbit but produces several spectral lines (R) : There are many excited energy levels available in a sample of Hydrogen gas

Assertion : Hydrogen has one electron in its orbit but it produces several spectral lines. Reason : There are many excited energy levels available. If both (A) and (R) are correct and (R) is the correct explanation of(A)., If both (A) and (R) are correçt, but (R) is not the correct explanation of (A)., If (A) is correct, but (R) is incorrect., If both (A) and (R) are incorrect.

In Hydrogen atom electron is present in the N shell. If it loses energy, a spectral line many be observed in the region

How many spectral lines are emitted by atomic hydrogen excited to the n-th energy level?

How many spectral lines are emitted by atomic hydrogen excited to the n-th energy level?

Assertion: Hydrogen atom consists of anly one electron but its emission spectrum has may lines. Reason: Only Lyman series is found in the absorption spectrum of hydrogen atom whereas in the emission spectrum, all the series are found.
