Those elements which have paired electrons are diamagnetic and weakly repelled by the external magnetic field. Cobalt is an important ferromagnetic metal. The six d electrons would therefore be How to Tell if a Substance is Paramagnetic or Diamagnetic. But strong-field ligands can split the energy levels of the d orbitals so that they are no longer degenerate. Therefore it has 4 unpaired electrons and would be paramagnetic. Cobalt(II) ions have three unpaired electrons. Textbook content produced by OpenStax College is licensed under a Creative Commons Attribution License 4.0 license. In other words, with a strong-field ligand, low-spin complexes are usually formed; with a weak-field ligand, a high-spin complex is formed. Titanium ion has unpaired electrons in orbital which makes it paramagnetic. Therefore it has 4 unpaired electrons and would be paramagnetic. O paramagnetic; seven unpaired electrons O diamagnetic; zero unpaired electrons O paramagnetic; three unpaired electrons paramagnetic; two unpaired electrons paramagnetic; zero unpaired electrons. Hunds' Rule states that electrons fill all available orbitals with single electrons before pairing up, while maintaining parallel spins (paired electrons have opposing spins). Randy Sullivan, University of Oregon Do EU or UK consumers enjoy consumer rights protections from traders that serve them from abroad? Articles from Britannica Encyclopedias for elementary and high school students. The strength of the paramagnetism of a coordination complex increases with the number of unpaired electrons; a higher-spin complex is more paramagnetic. How do you know if a molecule is paramagnetic or diamagnetic? Both complex ions contain the cobalt (III) cation, Co3+, which has the following electron configuration Co3+:1s22s22p63s23p63d6 Paramagnetic substances are atoms or molecules having unpaired electron(s).
