The element Cobalt, symbol Co, atomic number 27, atomic weight 58.9332, electron configuration [Ar]4s 2 3d 7 makes up, together with Fe and Ni, the group III B elements of the first row transition metals . The metal is hard, bluish-white (melting point 1493°C, boiling point 3100°C...
The core size of the porphyrin macrocycles was closely related to their stability of the different electron structure in the central metal ion. Cobalt(II) ions can undergo a conversion in electron configurations upon N4 core contraction of 0.05 Å in nonplanar porphyrins, and these ions still...
Having 1 more electron than ferrocene, it is paramagnetic with a magnetic moment of 1.76 BM and, while it is thermally stable up to 250°C, its most obvious characteristic is its ready loss of this electron to form the yellow-green cobalticenium ion, [CoIII(η5-C5H5)2]+. This resists...
A number of workers [1-4] have proposed a theoretical approach for analysis of the electronic absorption spectra of complexes with d~(d 3) electron configuration of the central ion in the strong field of ligands with C~ v and D~ h symmetry. The splitting parameters Dq, Dt, and Ds ...
The configuration of the outer electron shells of a cobalt atom is 3d74s2. In compounds cobalt exhibits alternating valence. In simple compounds, Co (II) has the highest degree of stability, and Co (III) is most stable in complex compounds. Only a few complex compounds of Co (I) and Co...
Cobalt Electron Configuration (Bohr Model) What is Cobalt Used for Cobalt is alloyed for use in gas turbine generators and jet turbines because of its high-temperature strength and resistance to corrosion[1, 4]. Cobalt is occasionally used in electroplating owing to its hardness and attractive app...
Cobaltous ion forms complexes with both octahedral and tetrahedral geometry (Burgess, 1999; Kerber and Goldberg, 2006). All Co complexes are octahedral and most involve nitrogen as the electron donor. The skeletal structure of the cobalamides can be visualized by representing the corrin ring of ...
