WebQ. Assertion (A) : Atoms with completely filled and half-filled subshells are stable. Reason (R) : Completely filled and half-filled subshells have the symmetrical distribution of electrons and have maximum exchange energy. Q. Assertion : Cu+ is less stable than Cu2+ but F e3+ is more stable than F e2+. WebIn the case of Cr and Cu, we find that half-filled and completely filled subshells apparently represent conditions of preferred stability. This stability is such that an electron shifts from the 4 s into the 3 d orbital to gain the extra stability of a half-filled 3 d subshell (in Cr) or a filled 3 d subshell (in Cu). Other exceptions also occur.
