Question

Which one is the wrong statement?

• A. de-Broglie's wavelength is given by \(λ=\frac {h}{mv}\), where \(m\) = mass of the particle, \(v\) = group velocity of the particle
• B. The uncertainty principle is \(△E × △t ≥ \frac {h}{4\pi}\)
• C. Half-filled and fully filled orbitals have greater stability due to greater exchange energy, greater symmetry and more balanced arrangement
• D. The energy of 2s orbital is less than the energy of 2p orbital in case of Hydrogen like atoms

Answer 1

The Correct Option is D

The correct option is (D): The energy of 2s orbital is less than the energy of 2p orbital in case of Hydrogen like atoms.
