Which one is the wrong statement?

Options

A. The energy of 2s orbital is less than the energy of 2p orbital in case of hydrogen like atoms
B. de-Broglie.s wavelength is given by `lambda=(h)/(mv)`, when m = mass of the particle , v = group velocity of the particle
C. The uncertainty principle is `DeltaE xx Deltat ge (h)/(4pi)`
D. Half-filled and fully filled orbitals have greater stability due to greater exchange energy, greater symmetry and more balanced arrangement

Answer

A

Explanation

The energy of 2s orbital is less than the energy of 2p orbital in case of hydrogen like atom is a wrong statement because:
`1s gt 2s = 2p gt 3s = 3p = 3d…` etc.
