All the hydrogen-like atoms in their ground states have the same
- A orbital angular momentum of the electron
- B energy of the atom
- C speed of the electron
- D radius of the orbit
Answer & Solution
Correct Answer
(A) orbital angular momentum of the electron
Step-by-step Solution
Detailed explanation
\( n = 1 \implies l = 0 \) \( L = \sqrt{l(l+1)}\hbar \) \( L = \sqrt{0(0+1)}\hbar = 0 \) orbital angular momentum of the electron
