Which one is the wrong statement ?

Options

A. The uncertainty principle is `Delta E xx Delta t ge h//4 pi`.
B. Half filled and fully filled orbitals have greater stability due to greater exchange energy, greater symmetry and more balanced arrangement.
C. The energy of `2s` orbital is less than the energy of `2p` orbital in case in Hydrogen like atoms.
D. de-Broglies's wavelength is given by `lamda = (h)/(mv)`, where `m=mass of the partilce, v = group velocity of the particle.

Answer

A

Explanation

( c) In `H-like` atom energy of `2 s = 2 p` Orbital
Incorrect statement is ( c).
