List of top Physics Questions on Bohr Model Of The Hydrogen Atom

The energy of an electron in an orbit in hydrogen atom is \( -3.4 \, \text{eV} \). Its angular momentum in the orbit will be:
Assertion : Energy is released when heavy nuclei undergo fission or light nuclei undergo fusion. Reason (R): For heavy nuclei, binding energy per nucleon increases with increasing \( Z \) while for light nuclei, it decreases with increasing \( Z \).
The radius of a nucleus of mass number 125 is:
An electron in the ground state of a hydrogen atom absorbs 12.09 eV energy. The angular momentum of the electron increases by

Calculate the change in angular momentum of an electron when it jumps from the third orbit to the first orbit in a hydrogen atom.
