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

STATEMENT-1: Half-filled and fully-filled degenerate orbitals are more stable. STATEMEHNT-2: Extra stabillity is due to the symmetrical distribution of electrons and exchange energy.

We know that fully filled and half filled orbitals are more stable. Can you write the electronic configuration of Cr(Z=24)?

Cu_((aq.))^+ has less stable nature than Cu_((aq.))^(2+) but Fe_((aq.))^(3+) is more stable than Fe_((aq.))^(2+) . Half-filled and completely filled, sub-shell are more stable.

The most stable orbitals are

Statement-1: Hybridisation is the mixing of atomic orbitals. Statement-2: In hybrididsation all types of atmoci orbitals half-filled,full-filled and vacant orbitals are participate.

Statement-1 : The third ionisation enthalpy of La, Gd and Lu are abnormally low. Statement-2 : Empty, half-filled and completelt filled orbitals of f-level are extra stable.

Assertion (A)Cr and Cu are extra stable in the 3d-series. Reason ( R) Half and completely filled set of orbitals are relatively more stable.
