Half filled subshells

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.

WebThe filling of the shells and subshells with electrons proceeds from subshells of lower energy to subshells of higher energy. This follows the n + ℓ rule which is also commonly known as the Madelung rule. Subshells … WebThe usual explanation in chemistry textbooks is that half-filled or completely filled subshells are particularly stable arrangements of electrons. [6] An example is chromium whose electron configuration is [Ar]4s 1 3d 5 with a d electron count of 5 for a half-filled d subshell, although Madelung's rule predicts [Ar]4s 2 3d 4.
