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

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

STATEMENT-1 : Principal Quantum number of outermost electron in Fe is 4. and STATEMENT-2 : Last electron is filled in 3d.

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.",):}

STATEMENT-1 : The 19^(th) electron in potassium atom enters into 4s-orbital than in 3d-orbital. and STATEMENT-2 : (n+1l) rule is followed for determining the orbital of lowest energy state.

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

Statement 1. 4s orbital has lower energy than 3d orbital. Statement 2. s-orbital is spherically symmetrical and remains closer to the nucleus and has lower energy than d-orbital.
