Hund's rule states that the most stable arrangement of electrons (for a ground state electron configuration) has a filled valence shell of electrons. Paramagnetic. Do clownfish have a skeleton or exoskeleton. The Pauli susceptibility comes from the spin interaction with the magnetic field while the Landau susceptibility comes from the spatial motion of the electrons and it is independent of the spin. Though arsenic is not so nature-friendly chemical element, it has various uses as a pesticide, herbicide, and insecticide. No, argon is not paramagnetic. If there is sufficient energy exchange between neighbouring dipoles, they will interact, and may spontaneously align or anti-align and form magnetic domains, resulting in ferromagnetism (permanent magnets) or antiferromagnetism, respectively. Arsenic is a paramagnetic compound because it has a total of 3 unpaired electrons in its 4p orbitals that are attracted by the external magnetic field and show weak magnetism.Unpaired Electrons of Arsenic. What is the maximum number of electrons that can occupy one p orbital? Such systems contain ferromagnetically coupled clusters that freeze out at lower temperatures. Because the atoms form double or triple bonds, the compounds tend to be stable and potentially toxic. Materials that are attracted by a strong magnet are known as paramagnetic materials. Diatomic oxygen, \(O_2\) is a good example of paramagnetism (described via molecular orbital theory). On the other hand, substances having all electrons paired, are termed diamagnetic.

Arsenic is a group-15 element and all these group-15 elements are known as pnictogens. A few atoms of the new element 113 were created in 2004 by a team of Russian and American scientists. It typically requires a sensitive analytical balance to detect the effect and modern measurements on paramagnetic materials are often conducted with a SQUID magnetometer. A paramagnet is a substance that is weakly attracted by the poles of a magnet. Let us discuss it in detail. Examples of the knowledge and application of ferromagnetism include Aristotle's discussion in 625 BC, the use of the compass in 1187, and the modern-day refrigerator. 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.
