Consider the following statements

(i) Spectral lines of ion belonging to Balmer series are not in visible range.

(ii) In the Balmer series of H -atom maximum lines are in ultraviolet region.

(iii) line of " Lyman series of ions has energy " 48.35 eV "

The above statements (i),(ii),(iii) respectively are (T= True,"F=" False)

Options:

Answer:
C
Solution:

Statement (i) is True. For ions, the energy levels are shifted, causing Balmer lines to fall outside the visible range.

Statement (ii) is False. The Balmer series for H-atom has lines predominantly in the visible region, with only higher energy lines extending into the UV.

Statement (iii) is True. The energy of the first line (n=2 to n=1) of the Lyman series for a He+ ion (Z=2) is approximately 48.35 eV.
