There are _ distinct series of Hydrogen spectrum:
Correct answer: C. 5
- A. 1
- B. 3
- C. 5
- D. 7
Explanation
There are 5 distinct series of hydrogen spectrum: Lyman, Balmer, Paschen, Brackett, and Pfund. Each series is named after the scientist who first observed it and the principal quantum number of the orbit that the electron falls to. The different series of hydrogen spectrum are produced when an electron in an atom falls from an outer orbit to a lower orbit. The different series of hydrogen spectrum can be used to study the structure of the hydrogen atom and to measure the distance between stars and galaxies.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
