Structure Of Atom

Question
CBSEENCH11008455

Which one is the wrong statement?

  • de-Broglie's wavelength is given by λ = h/mv,
    where m = mass of the particle, v = group velocity of the particle

  • The uncertainty principle is increment straight E space straight x space increment straight t space greater or equal than space fraction numerator straight h over denominator 4 straight pi end fraction

  • 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

Solution

D.

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