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.
