Question

how many maximum spectral lines can be expected in visible
electronic transition from fifth shell to first shell of H2 atom of
2 atom

Dear student

Here we need to use the concept of hydrogen spectra to get the
answer for the maximum number of the lines lying in the visible
region As we know the transitions are taking from n = 5 to the
ground state So if we take into account, just one atom, the total
number of spectral lines will be 10

Out of these only the lines lying in the balmer region will be
visible These are (5 to 2), (4 to 2) and (3 to 2)
so for one atom, there will be three lines and for a molecule
containing two atoms there will be a total of (3)(2) = 6 visible
lines
