Question

The ultraviolet spectral region is obtained in Balmer series.

(a) True

(b) False

I have been asked this question by my school principal while I was bunking the class.

I'd like to ask this question from Developments Leading to the Bohr’s Model of Atom topic in division Structure of Atom of Chemistry – Class 11

Answer 1

Correct choice is (b) False

Explanation: When an electron jumps from n^th orbit to 1st orbit, provided that n = 1, 2, 3, etc, it emits radion in the ultraviolet region. As per the spectral lines of the hydrogen, when an electron jumps from n^th orbit to 2^nd orbit, it’s in Balmer series (provided that n = 3, 4, 5….). For Balmer series, the electron emits waves in the visible region.
