Indeed, all substances are diamagnetic: the strong external magnetic field speeds up or slows down the electrons orbiting in atoms in such a way as to oppose the action of the external field in accordance with Lenz’s law. IMFs; 4. paramagnetic or diamagnetic, respectively. Lanthanoid ion with no unpaired electron is diamagnetic in nature. [Fe(H2O)6]2+ is paramagnetic since H2O is a weak field ligand, this means there is a small energy gap between the t2g and eg and so promoting electrons to the eg becomes energetically favourable above putting 2 electrons in the same oribtal. Now, the ligand NH3 is a strong field ligand and hence it is a low spin complex. (Atomic no. Chemistry. Crystal Field Theory [NiCl4]^2 - is paramagneti... chemistry [N i C l 4 ] 2 − is paramagnetic while N i (C O) 4 ] diamagnetic though both are tetrahedral. Electron configurations for the first period. Answer. Mathematics. Diamagnetism is a quantum mechanical effect where the lack of unpaired electrons allows for an induced magnetic field that repels an applied magnetic field. Google Classroom Facebook Twitter. Gases; 2. Classify each of these ions as diamagnetic or paramagnetic.Diamagnetic substances contain no net electron spin and are repelled from a magnetic field. 0. Consequently, octahedral Ni(II) complex with strong field should be diamagnetic. Learning Strategies The diamagnetic shift of excitons is a convenient means to evaluate the exciton wave-function extension also for quantum wires. So if current is moving in this direction in a loop of wire, so I represents current, a magnetic field is created. Sign up to join this community . Large negative values are aromatic, for example, benzene (Λ = −13.4). 1. Ask a chemist › Category: Other › why-is-phosphorus-diamagnetic 0 Vote Up Vote Down Jay asked 3 months ago Question Tags: phosphorous chemistry focus on the determination of the number of un-paired electrons in various transition-metal salts (1–6).
