86. Solving a chemistry problem

8. For the following complex particles (intraorbital - in bold):
8. [CuCl2]-, [SnCl5]-, [CoCl4]2-, [Co(H2O)6]3;

a. draw schematically the electronic configuration of the central complexing atom in the ground state, then the complexing ion;
b. determine the type of hybridization of the orbitals of the complexing ion and the spatial configuration of the particle;
in. determine whether the particle is paramagnetic or diamagnetic, calculate its magnetic moment (spin component) in Bohr magnetons.
