Nickel ion (Ni2+) is a typical transition metal ion with the outer electron configuration of 3d8. The free Ni2+ ion possesses states of 3F, 1D, 3P, 1G and 1S. According to ligand field theory, these states would spilt when Ni2+ located in the specific crystal positions. As an exampl...
The nickel(II) ion has a d 8 electronic configuration and, with weak-field ligands such as H 2 O, it forms a six-coordinate ion with approximately octahedral symmetry and a paramagnetic (two unpaired electrons) 3 A 2 ground state. The X-ray crystal structures of a variety of high- and...
Electron configuration dispute Nickel has two atomic electron configurations, [Ar] 3d8 4s2 and [Ar] 3d9 4s1, which are very close in energy; [Ar] denotes the complete argon core structure. There is some disagreement on which configuration has the lower energy.[17] Chemistry textbooks quote ...
Substantial magnetic moments of Ni-IV, which is intrinsically nonmagnetic with a nominal d(6) electron configuration, were induced by the large magnetic moments of Fe-IV through orbital hybridization with oxygen. As a result, ferromagnetism with the transition temperature (T-c) above room ...
The electronic configuration of isolated nickel atom is counterintuitive: direct investigation[3] finds that the predominant electron structure of nickel is [Ar] 4s1 3d9, which is the more stable form because of relativistic effects. Whereas Hund's rule, which works well for most other elements,...

From total energy considerations it emerges that, in their ground state, both LiNiO2 and NaNiO2 are insulators, with the Ni ion in the Ni3+ low-spin state (t(2g)(6)e(g)(1)) configuration. It is established that a substitution of a number of Li/Na atoms by divalent impurities ...
The RNiO3 series exhibits a MIT with transition temperatures strongly varying with the R ion size11. For R=La the material remains metallic at all temperatures, whereas for a smaller ionic radius of the R ions, a higher MIT temperature is found. At high temperatures, the crystal symmetry is...
Molecularly-selective metal separations are key to sustainable recycling of Li-ion battery electrodes. However, metals with close reduction potentials present a fundamental challenge for selective electrodeposition, especially for critical elements such as cobalt and nickel. Here, we demonstrate the synergist...
Electroless nickel–phosphorus (Ni–P) deposits are produced from theelectrochemical reductionof anickel ionthrough theautocatalytic platingprocesses in the plating solution. Theelectroless platingprocess that led to the practical application of these deposits was first developed by Brenner and Riddell, and...
