1.
[NEET 2020-type] Which of the following represents the Heisenberg uncertainty principle in an alternative form?
2.
**Assertion (A):** An electron cannot have the quantum numbers n=3, l=3. **Reason (R):** The azimuthal quantum number l must always be less than the principal quantum number n.
3.
**Assertion (A):** de Broglie's concept explains Bohr's quantization of angular momentum. **Reason (R):** The condition nλ = 2πr_n (standing wave) is equivalent to mvr = nh/2π.
4.
**Assertion (A):** The Balmer series has more spectral lines than the Lyman series. **Reason (R):** The Balmer series includes all transitions to n=2, while Lyman only includes transitions to n=1.
5.
**Assertion (A):** The concept of definite orbits in Bohr's model is inconsistent with the Heisenberg Uncertainty Principle. **Reason (R):** In Bohr's model, both position and momentum of an electron in an orbit can be determined simultaneously.
