Web11 apr. 2024 · The magnetic characteristics are caused by unpaired electrons in (n-1) d orbitals. As the number of unpaired electrons grows from one to five, the paramagnetic property of transition metals increases from left to right. The maximum paramagnetic property is seen in the intermediate elements. Web9 okt. 2024 · The magnetic form of a substance can be determined by examining its electron configuration: if it shows unpaired electrons, then the substance is paramagnetic; if all electrons are paired, the substance is diamagnetic. This process can be broken into four steps: Find the electron configuration Draw the valence orbitals Look for unpaired electrons WebParamagnetic substances are those in which each atom or molecule has a net non-zero magnetic moment of its own. 1.
