Write the electronic configuration of cobalt ion in [CoF6]³‐ and predict its magnetic behaviour​

Answer»

Answer:

Answer. - Co (Z=27) has electronic configuration [Ar] 3d7 4S2. - In [(CoF6)3-] complex, Co donates 3 e- to form CO3+ ion to which 6 F- LIGANDS SURROUND. ... - 4 free ELECTRONS are present in 3d orbitals of Co, thus it shows paramagnetic behavior.
