One of the lines in the emission spectrum of \( \mathrm{Li}^{2+} \) has the same wavelength as that of the second line of Balmer series in
\( \mathrm{P} \) hydrogen spectrum. The electronic transition corresponding

W to this line is
(1) \( n=4 \rightarrow n=2 \)
(2) \( n=8 \rightarrow n=2 \)
(3) \( n=8 \rightarrow n=4 \)
(4) \( n=12 \rightarrow n=6 \)
