Extra Stability OF Half Filled and Fully Filled Orbitals /Symmetry /Exchange Enegy/Calculation OF Total Number OF Exchanges (JH Shortcut)

Stability Of Completely Filled And Half Filled Orbitals

Half-filled and fully-filled orbital orbitals are more stable

The extra stability of half-filled and completely-filled subshell is due to

Rules OF Filling OF Electrons || Aufbau's Principle || (n+l) rule || Hund's Rule OF Maximum Multiplicity || Pauli's Exclusion Principle || Reason OF Stability OF Half filled and Fully filled Orbitals || Electronic Configuration OF First 30 elements

Which of the following has fully filled f-orbitals ?

The correct order of relative stability of half filled and completely filled sub-shell is

The correct statements among the following (i) E_(2s)(H)>E_(2s)(Li)>E_(2s)(Na)>E_(2s)(K) (ii) The maximum number of electrons in the shell with principal quantum number n is equal to 2n^2 . (iii) Extra stability of half-filled subshell is due to smaller exchange energy (iv) Only two electrons, irrespective of their spin, may exist in the same orbital are
