Half-filled and fully filled orbitals have extra stability. Explain.

Half filled and completely filled orbitals have extra stability. Why?

Match the following rules with their statement : {:(,"Rules",,"Statements",),(("a"),"Hund's Rule",("i"),"No two electrons in an atom can have the same set of four quantum numbers.",),("(b)","Aufbau Principle",("ii"),"Half-filled and completely filled orbitals have extra stability.",),("(c)","Pauli Exclusion Principle",("iii"),"Pairing of electrons in the orbitals belonging to the same subshell does not take place until each orbital is singly occupied.",),(("d"),"Heisenberg's Uncertainty","(iv)","It is impossible to determine the exact position and exact momentum of a subatomic particle simultaneously.",),(,,("v"),"In the ground state of atoms, orbitals are filled in the order of their increasing energies.",):}

Explain why atoms with half filled and completely filled orbitals have extra stability.

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

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.
