Question

Which one of following is a wrong statement? (A) The uncertainty principle is Δ E× Δ t≥ h/4π  (B) Half filled and fully filled orbitals have greater stability due to greater exchange energy, greater symmetry and more balanced arrangement. (C) The energy of 2s orbital is less than the energy of 2p orbital in case of Hydrogen like atoms. (D) De-Brogliesâs wavelength is given by λ =(h/m v), where m = mass of the particle, v = group velocity of the particle.

In case of Hydrogenic species is 1s < 2s = 2p < 3s = 3p = 3d Hence, 2s and 2p have same energy for Hydrogenic species. The rest of the statements are correct.

Q. Which one of following is a wrong statement?

The uncertainty principle is $Δ E \times Δ t \geq h /4 π$

Half filled and fully filled orbitals have greater stability due to greater exchange energy, greater symmetry and more balanced arrangement.

The energy of 2s orbital is less than the energy of 2p orbital in case of Hydrogen like atoms.

De-Broglies’s wavelength is given by $λ = \frac{h}{m v},$ where m = mass of the particle, v = group velocity of the particle.

In case of Hydrogenic species is 1s < 2s = 2p < 3s = 3p = 3d
Hence, 2s and 2p have same energy for Hydrogenic species.
The rest of the statements are correct.
