Vedclass · Accepted Answer

Orbital angular momentum of the electron.

Vedclass · Answer

(D) According to Bohr's postulate,the orbital angular momentum $L$ of an electron in a hydrogen atom or a hydrogen-like ion is given by the formula:$L = \frac{n h}{2 \pi}$where $n$ is the principal quantum number,$h$ is Planck's constant,and $\pi$ is a mathematical constant.For the ground state,the principal quantum number is $n = 1$ for all hydrogen-like atoms and ions.Since $h$ and $\pi$ are universal constants,the value of $L$ for $n = 1$ is $L = \frac{h}{2 \pi}$,which is independent of the atomic number $Z$.Therefore,the orbital angular momentum of the electron is the same for all hydrogen-like atoms and ions in their ground state.

The following parameter is the same for all hydrogen-like atoms and ions in their ground state.
