Rh +, Ir +, Pd 2+, Pt 2 +, and Au 3+ complexes with a d 8 configuration tend to form square planar structures because eight electrons occupy the lower orbitals leaving the highest d x 2-y 2 … 8th Edition. How are electrons distributed in the atom? The periodic table 3. The elements having configuration against Auf-bau rule are called to have abnormal configuration. Platinum Electronic configuration. 20 pt … The periodic table can be a powerful tool in predicting the electron configuration of an element. As a result, the fourth electron enters one of the eg orbitals, thereby, exhibiting the electronic configuration t2g3 eg1. [Xe]6s 2 4f 7 5d 1 But why? And then we can write the electron configuration really short, or it'll be really short because we know it's going to lose these two valence electrons and then, it will have the electron configuration which is just the same as argon. For example, the configuration of magnesium could be written [Ne]3s 2, rather than writing out 1s 2 2s 2 2p 6 3s 2. On the basis of crystal field theory, for a d4 ion, if ∆o< P, then the complex is a high spin complex formed by the association of weak field ligands with the metal ion. For example, the electron configuration of lithium, 1s²2s¹, tells us that lithium has two electrons in the 1s subshell and one electron in the 2s subshell. The atomic configuration of each atom is assumed to be neutral, with platinum and chalcogen atoms having d9s’ and s2p4 configurations respectively.
