Which one is the wrong statement ?

Options

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

Answer

C

Explanation

The enrgy of 2s-orbital and 2p-orbital is equal in hydrogen like atoms.
