Question

A Hydrogen atom is a low density hot gas will give out what type of spectrum?A. A uniform spectrum containing all colorsB. A series of emission lines with equal spaces between the colorsC. A series of emission lines spaced in mathematical sequenceD.a uniform spectrum crossed by numerous dark absorption lines

Answer 1

The emission of photons takes place when an electron from higher energy orbitals jumps to a lower energy orbital.

Therefore the light emitted will correspond to the energy difference between the orbitals.

When the atom emits the photons, they will have energy equal to the energy difference between the orbitals of the Hydrogen. Therefore the spectrum obtained by the hydrogen gas will contain only those lines which correspond to the energy difference of the orbitals.

Therefore the hydrogen will emit a spectrum that contains a series of emission lines spaced in a mathematical sequence.

Therefore the correct answer is option C.
