Question

How to know if a given element is paramagnetic?

Answer 1

Hint :In order to the question, to know whether the element is paramagnetic or not, we should go through the whole explanation of paramagnetic. We will also discuss the example of the property Paramagnetic.

Complete Step By Step Answer:
Paramagnetic elements are strongly affected by magnetic fields because their subshells are not completely filled with electrons.
Paramagnetism refers to a property of certain materials that are weakly attracted to magnetic fields. When exposed to an external magnetic field, internal induced magnetic fields form in these materials that are ordered in the same direction as the applied field. Once the applied field is removed, the materials lose their magnetism as thermal motion randomizes the electron spin orientations.
Materials that display paramagnetism are called paramagnetic. Some compounds and most chemical elements are paramagnetic under certain circumstances. However, true paramagnets display magnetic susceptibility according to the Curie or Curie-Weiss laws and exhibit paramagnetism over a wide temperature range. Examples of paramagnets include the coordination complex myoglobin, transition metal complexes, iron oxide $ \left( {FeO} \right) $ , and oxygen $ ({O_2}) $ . Titanium and aluminum are metallic elements that are paramagnetic.

Note :
Most elements and some compounds are paramagnetic. Strong paramagnetism (not to be confused with the Paramagnetism, a kind of magnetism characteristic of materials weakly attracted by a strong magnet, named and extensively investigated by the British scientist Michael Faraday beginning in 1845.
