Class Notes . Water is paramagnetic, which means that it has a slight magnetic moment, because the last two electrons in oxygen's shell are unpaired and each one is in the p_x* and p_y* orbitals. Electrons not only go around the atom in their orbitals, they also spin, which creates a magnetic field. A) Most elements and some compounds are paramagnetic. Paramagnetic Paramagnetism is a form of magnetism whereby certain materials are weakly attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field. This strange behaviour can be explained by MOT. Report ; Posted by Riyank Kakkar 52 minutes ago. This capability allows paramagnetic atoms to be attracted to magnetic fields. Why is the molecular structure of water bent? Because of their opposite spins they produce magnetic field in opposite direction thus the resultant magnetism becomes zero. Reason: The bond length of N 2 , is shorter than that of oxygen. 420 terms. 2SO2(g)+ O2(g)⇌2SO3(g); ∆= - 42k.cal. You can see Oxygen gets attracted toward the magnetic field while Nitrogen repels it. D. The ionization potential of N is 14.54 eV and that for F is 17.42 eV. Consequently, it is attracted into a magnetic field, which allows it to remain suspended between the poles of a powerful magnet until it evaporates. Does this mean you would use the MO diagram for Z<8?

Electrons not only go around the atom in their orbitals, they also spin, which creates a magnetic field. 7.06.2.6 Electron Paramagnetic (or Spin) Resonance Spectroscopy. Water has no unpaired electrons and is thus diamagnetic. In the case of Ti, there are four valence electrons, two in the 4s and two in the 3d. QED dictates that the magnetic moment of an electron arises from its properties of spin and orbital motion, giving it angular momentum in the quantum sense. Paramagnetic and diamagnetic character of substance depends on the number of unpaired and paired electrons occupied by that substance.. Any substances those contain number of unpaired electrons are called paramagnetic substances. This strange behaviour can be explained by MOT.
