Question

2) Which of the following produces a band spectrum

when excited?

A) Na

B) H2

C) Ne

D) He​

Answer 1

Answer:

B) H2 :is. your answer as we have Hydrogen Spectrum.

Answer 2

Answer:

• Helium and Hydrogen both produces the spectrum, but the spectrum of Helium is more complicated than hydrogen.

• Since hydrogen has only one electron, its spectrum is simpler.

• The single electron has a limited number of quantum states whereas this is not the case with Helium which has more electrons.

• When compare the spectrum, then helium has a more complex spectrum than hydrogen which has only one electron.
