As an electron makes a transition from an excited state to the ground state of a hydrogen - like atom/ion
kinetic energy decreases, potential energy increases but total energy remains same
kinetic energy and total energy decrease but potential energy increases
its kinetic energy increases but potential energy and total energy decrease
kinetic energy, potential energy and total energy decrease
What is impact parameter ?
If the force between the electron in the first Bohr orbit and the nucleus (proton) in hydrogen atom is $F$, then the force between them when the electron is in the second orbit is
Assertion $(A)$ : The magnetic moment $(\mu)$ of an electron revolving around the nucleus decreases with increasing principle quantum number $(n)$.
Reason $(R)$ : Magnetic moment of the revolving electron, $\mu \propto n$.
The ratio of ionization energy of Bohr's hydrogen atom and Bohr's hydrogen like lithium atom is
