The uncertainty principle is

$$\Delta E \times \Delta t \ge {h \over {4\pi }}$$

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.

de-Broglie's wavelength is given by

$$\lambda = {h \over {mv}}$$, where m = mass of the particle,

v $$=$$ group velocity of the particle.
