A diamagnetic material has a permeability less than that of a vacuum. * All of these 10 electrons are pushed into 3d orbitals and get paired up when strong field CO ligands approach Ni atom. This is a balance with a strong electromagnet placed next to the sample holder. (Atomic number of Ni = 28) In [NiCl 4] 2-, due to the presence of Cl - a weak field ligand no pairing occurs whereas in [Ni(CN) 4] 2-, CN - is a strong field ligand and pairing takes place/diagrammatic represenlation. What is Paramagnetic and Diamagnetic ? Hence [Fe(H2O)6]2+ is more paramagnetic. Why is [Ni(NH 3) 6]Cl 2 paramagnetic but [Co(NH 3) 6]Cl 3 is diamagnetic ? See the answer. * In presence of water, which is a weak field ligand, the configurations of metal ions in hydrated compounds reflect those in isolated gaseous ions i.e., no pairing of electrons is possible as the interaction with water molecules is weak. It is found, that except for [CoF6]^3-, Co(III) cmplxs are low spin with a large Δoct (>P pairing energy) hence the 6 e- fully occupy the t2g set (triply degenerate) of AOs: ↑↓↑↓↑↓ All the e-s are paired and so this cmplx is diamagnetic. Here a pyrolytic carbon sheet is levitated by its repulsion from the strong magnetic field of neodymium magnets. An atom could have ten diamagnetic electrons, but as long as it also has one paramagnetic electron, it is still considered a paramagnetic atom. ...

Why don't libraries smell like bookstores? In [CoF6]3–, Co is having four unpaired electrons as F– does not cause pairing of electrons in d-orbitals, whereas in case of [Co(C2O4)3]3–, C2O4 causes pairing of unpaired electrons in d–orbitals and thus there is no unpaired electron, hence it is diamagnetic in nature. Salt: Diamagnetic. 1) How do you calculate the magnetic moment of ions of transition elements? … In contrast, ferromagnetic and paramagnetic materials are attracted to … Yes. Each orbital within an atom can only hold a … The diamagnetic and paramagnetic character of a substance depends on the number of odd electron present in that substance. usually too small to notice. Now, the ligand NH3 is a strong field ligand and hence it is a low spin complex. Paramagneticcompounds contain one or more unpaired electrons and are attracted to the poles of a magnet. Magnetic Properties of Atoms: Electrons spin, which generates a small magnetic field. Explanation: Ni exist in zero oxidation state so its configuration is - its configuration is - – CO is strong ligand so pairing of electron possible and configuration will be – Number of unpaired electron are zero hence it is diamagnetic in nature.
