Notes of “The Atomic Structure of Hydrogen Atom” for BSc written by Mr.Nasir Pervaiz Butt. These notes are very helpful to prepare Modern Physics for BSc and are in accordance with paper pattern of Punjab University-Lahore, GCU-Lahore, GCU-Faislabad, University of Sargodha-Sargodha and all other universities of Punjab and Pakistan.

A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the elemental (baryonic) mass of the universe…
