CHXI02:STRUCTURE OF ATOM

307560 Statement A :
For Balmer series of hydrogen spectrum, the value \({{\rm{n}}_{\rm{1}}}{\rm{ = 2}}\) and \({{\rm{n}}_{\rm{2}}}{\rm{ = 3,4,5}}{\rm{.}}\)
Statement B :
The value of n for a line in Balmer series of hydrogen spectrum having the highest wavelength is 4 and 6.

CHXI02:STRUCTURE OF ATOM

307561 Assertion :
In Lyman series of H-spectrum, the maximum wavelength of lines is \(\mathrm{121.56 \mathrm{~nm}}\).
Reason :
Wavelength is maximum if there is transition from the very next level.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
CHXI02:STRUCTURE OF ATOM

307562 Assertion :
The transition of electrons \(\mathrm{n}_{3} \rightarrow \mathrm{n}_{2}\) in \(\mathrm{H}\)-atom will emit greater energy than \(\mathrm{n}_{4} \rightarrow \mathrm{n}_{3}\).
Reason :
\({{\text{n}}_{\text{3}}}\) and \({{\text{n}}_{\text{2}}}\) are closer to nucleus than \(\mathrm{n}_{4}\).
