4. For each of the Mn complexes in the table below, give electronic configurations (within the t2g and eg sets of 3d orbitals) that are consistent with the observed magnetic moments. u (BM) 1.8 Compound [Mn(CN)6]4 [Mn(CN)6]3- [Mn(NCS)6]4- [Mn(acac)3] 3.2 6.1 5.0
1. When do we have magnetic property? 2. What is the origin of magnetism? 3. Define what is the magnetic dipole moment? 4. Explain the magnetization connecting with the magnetic dipole moment. 5. Explain about the magnetic hysteresis curve of ferromagnetism materials. Describe the shapes of magnetization at specific points and explain the names of the points and the meaning.
4. The complexes (Mn(H2O).], [Fe(H2O))", [MnCl] and [FeCl.] all have magnetic moments near 5.92 BM. Explain with correct geometry and electronic structure.
In relation to M(acac)3 complexes, assuming they contain an octahedrally coordinated M3+ ion: Draw the ligand field orbital diagrams for Co(III), Fe(III), Mn(III), and Cr(III) to derive the possible electron configurations for the metal complexes. State the number of unpaired spins each configuration has. Which is the correct d-electron configuration for each complex? Which complexes are "high spin" and which are "low spin"? Thanks so much! I will give immediate upvotes!
For an Mn based ferrite, MnFe2O4, the magnetic moment comes from Mn. Given that the saturation magnetization of MnFe2O4 is 5.6×105 A/m, the atomic weight is 230.64 g/mol and density is 5.0 g/cm3. Calculate the number of Bohr magnetons per Mn2+ ion.
what is the point group of [Cr(acac)3]Cl3 and [Cr(en)3]Cl3?
A Review Constants Periodic Table Learning Goal: To use electron configuration to explain magnetic behavior. Electron configuration The magnetic behavior of an atom or ion depends on its electron configuration. An important property that results from the electron configuration of an atom or an ion is behavior in the presence of an external magnetic field. Due to the random orientations of electron spins most materials have no permanent magnetic effect without an external magnetic field. Part A Select the correct...
