Incorrect statement among the following is:
1. | The uncertainty principle is\(\Delta x \cdot \Delta p \geq \dfrac{h}{4 \pi} \) |
2. | Half-filled and fully filled orbitals have greater stability due to greater exchange energy, greater symmetry, and a more balanced arrangement. |
3. | The energy of the 2s orbital is less than the energy of the 2p orbital in the case of hydrogen-like atoms. |
4. | De-Broglie's wavelength is given by\(\lambda=\dfrac{h}{m v} \), where m= mass of the particle, v = group velocity of the particle. |
