1.Which one of the following statements is wrong?a.de-Broglie's wavelength is given by λ=h/(mv)\lambda = h/(mv)λ=h/(mv), where mmm = mass of the particle, vvv = group velocity of the particle.b.The uncertainty principle is ΔE×Δt≥h/4π\Delta E \times \Delta t \geq h/4\piΔE×Δt≥h/4π.c.Half-filled and fully-filled orbitals have greater stability due to the 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.Login to continueOnly logged in users canattempt or see the solution.
