Understanding Angular Momentum in Hydrogen and Lithium
In quantum mechanics, the angular momentum of an electron in an atom is quantized and is given by the formula:
L = n * ħ
where:
- L is the angular momentum,
- n is the principal quantum number,
- ħ is the reduced Planck's constant.
Angular Momentum in Hydrogen
- For hydrogen (H), which has one electron:
- The ground state corresponds to n = 1.
- Therefore, L1 = 1 * ħ = ħ.
Angular Momentum in Lithium
- In the case of lithium (Li), when it is double ionized (Li2+), it has lost two electrons:
- The remaining single electron is in the first orbit, also with n = 1.
- Therefore, L2 = 1 * ħ = ħ.
Comparison of Angular Momentum
- From the calculations:
- L1 = ħ (for hydrogen)
- L2 = ħ (for lithium)
- Thus, we can conclude:
- L1 = L2
Conclusion
- The correct answer to the question is option 'A': L1 = L2.
- Both the ground state of hydrogen and the first orbit of double ionized lithium have the same angular momentum value, which is ħ.
