to lose the 6th shell electrons rather than the perfect 5d10 setup. 1. square planar; d(xy) and d(x 2-y 2) 2. sodium tetrachloroplatinate (II) 3. Comprehensive information for the element Platinum Pt is provided by this page including scores of properties, element names in many languages, most known nuclides and technical terms are linked to their definitions. 6s1. A brief introduction to orbital diagrams and electron configurations Explanation: Platinum is atomic number 78, which means that all Pt atoms … Draw the d-electron configuration for the chloride complex ion of Pt(IV). So if that's wrong it might be, [Xe] 4f14 5d9 6s1 . 4s2 4p6 4d10 4f14. The ground state electron configuration of ground state gaseous neutral platinum is [Xe].4f 14.5d 9.6s 1 and the term symbol is 3 D 3. But like most of the transition metals it achieves a pseudo-noble gas electron configuration, only two of those electrons are involved in bonding, the two 6s electrons. It appears to be 2, 8, 18, 32, 17, 1, which translates to. 2p2 2p6. ... Electron Configuration: 1s 2 2s 2 p 6 3s 2 p 6 d 10 4s 2 p 6 d 10 f 14 5s 2 p 6 d 9 6s 1; A rule of thumb is that half-filled shells are stabilized. So that means in the case of $\ce{Pt}$, $\mathrm{[Xe] 4f^{14} 5d^9 6s^1}$. But $\ce{Pt}$ is an exception (as there are some). 5s2 5p6 5d9. It comes from relativistic effects, electron correlation and shielding effects. It turns out that the energy the electron configuration that is half-filled, 4s 1 3d 5, and filled orbital, 4s 1 3d 10, has lower energy than the typical filling order, 4s 2 3d 4, and 4s 2 3d 9.This pattern is followed in the 5 th row with Mo (#42) and Ag (#47). Electronic configuration of Pt is [Xe] 4f14, 5d9 , 6s1. Periodic Table Exceptions To Know. Explain the difference between this configuration and that of Pt(II), Is the Pt(IV) chloride complex ion paramagnetic or diamagnetic? Electron configuration The arrangements of electrons above the last (closed shell) noble gas. That is, whereas we would expect that it be 6s2 5d8, an electron was taken from the s orbital and placed in the d orbital instead. Atomic number of Platinum is 78. The shorthand electron configuration of Pt is #["Xe"]"4f"^14"5d"^9"6s"^1"#. ... 190 Pt 189.960 0.012 4.5 x … 3s2 3p6 3d10. One such alloy made of 76.7% Pt and 23.3% Co, by weight, is an extremely powerful magnet that offers a B-H (max) almost twice that of Alnico V. Platinum resistance wires are used for constructing high-temperature electric furnaces. And for Pt what you got is right. Melting point The temperature at which the solid–liquid phase change occurs. Platinum-cobalt alloys have magnetic properties. 1s2. Platinum is the element present in d - block element . Pt(II) can be oxidized to Pt(IV). There is a major exception to the normal order of electron configuration at Cr (#24) and Cu (#29). Schematic electronic configuration of platinum. The real answer is much more complicated.
