Which one is the wrong statement ?

1.	Which one is the wrong statement ?
Answer» de-Broglie's wavelength is given by `lamda = (h)/(mv)` where m is the mass of the particle, `v =`groups velocity of the particle The uncertainty principle is `Delta E XX Delta t ge (h)/(4pi)` Half-filled and fully-filled orbitals have greater stability due to greater exchange energy, greater SYMMETRY and more BALANCED arrangement The energy of 2S orbitals is LESS than the energy of 2p orbital in case of hydrogen like atoms Solution :Energy of 2s and 2p orbitals is equal in case of hydrogen like atoms.
