Paramagnetism . Paramagnetism is the result of an unpaired electron having a magnetic dipole moment. This means that the diamagnetic effect per electron must be less than one-twelfth of the paramagnetic effect per electron. They also show paramagnetism regardless of the temperature range. Wachs, C.J. First observed by S.J. (1) Diamagnetic definition is - having a magnetic permeability less than that of a vacuum : slightly repelled by a magnet. Here is a worked example problem showing how to tell whether an element is paramagnetic or diamagnetic based on its electron configuration. The diamagnetic contribution from the valence electrons is small, but from a closed shell it is proportional to the number of electrons in it and to the square of the radius of the ‘orbit’. ... you'll see that meets the standard definition of diamagnetism.

And so a diamagnetic sample would not be attracted to an external magnetic field. Definition of Diamagnetic 1) a diamagnetic material has no unpaired spins; when such a material without permanent dipoles has a magnetic field applied to it, the magnetic dipoles induced in the material line up opposite to that of the induced field. Return to top of page. In many metals this diamagnetic effect is outweighed by a paramagnetic contribution, the origin of which is to be found in the electron spin. General Chemistry Glossary. This correction is often accomplished by using tabulated values for the diamagnetism of atoms, ions, or whole molecules. Examples of how to use “diamagnetic” in a sentence from the Cambridge Dictionary Labs Compounds are diamagnetic when they contain no unpaired electrons.Molecular compounds that contain one or more unpaired electrons are paramagnetic.The magnitude of the paramagnetism is … Chelate complex-definition-examples-chelating and π-acid ligand’s . Return to top of page. Through-space interaction between magnets of fixed strength and orientation averages to zero during random molecular tumbling, suggesting that the local field about a proton should be sensitive only to electrons that orbit about itself. So we have these two definitions. Diamagnetic Anisotropy Definition: An effect that causes different regions of space to be characterized by different magnetic field strengths. So it's actually weakly repelled by an external magnetic field. Nonetheless, true paramagnets are those materials that show magnetic susceptibility with respect to the Curie law. Diamagnetic atoms have only paired electrons, whereas paramagnetic atoms, which can be made magnetic, have at least one unpaired electron. Look it up now!
