Which one is a wrong statement?

1.	Which one is a wrong statement?
Answer» the uncertainty principle is `DeltaE xxDeltat ge(h)/(pi)` 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 Broglie's wavelength is given by `LAMDA=(h)/(mv)`, where m=mass of the particle, v=group VELOCITY of the particle Solution :For hydrogen like atom, energy of the orbital depends on the principal quantum number. THUS for hydrogen like atom, energy of 2s and 2p orbitals are same.
