25 Jul 2019 The answer is [Ar] 4s1 3d5 Because half-filled subshells are somewhere stable, the atom prefers to have a half-filled 4s and half-filled 3d's than Answer to How is the electron configuration of Cr3+ 1s2 2s2 2[6 3s2 3p6 3d5 4s1 [Ar]3d5 4s1 [Ar]3d3 The corresponding atom is chromium and its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s1 3d5 or [Ar] 4s1 3d5 in shortened notation. 某基態正三價離子的電子組態，最高能量的軌域及所含電子數為3d5，則該原子的原子序為何者？ (A)26Fe3＋：[Ar] 3d5 (B)30Zn2＋：[Ar] 3d84s2 (C)24Cr：[Ar] 3d44s2 (C)Cr：[(A)r] 3d44s2→Cr：[Ar] 3d54s1 (D)Cu：[Ar] 3d104s1→Cu：[Ar ] 20 Oct 2017 It boils down to an increase in exchange energy and decrease in repulsion energy being enough that the 3d orbitals are lower in energy than the 1s2 2s2 2p6 3s2 3p6 3d5 4s1. For the Cr2+ ion we remove one electron from 4s1 and one from the 3d5 leaving us with: 1s22s22p63s23p63d4. For the Cr3+ ion Au3+ - [Xe] 6s0, 4f14, 5d8 b. Co3+ - [Ar] 4s1, 3d5. Fe3+ - [Ar] 4s0, 3d5. Zn2+ - [Ar] 4s0, 3d10.
