Complete the following electronic configurations. • the cobalt atom, Co 1s22s22p6 • the cobalt(ion, Co2+ 1s22s22p6 State the colours you would observe when concentrated HCl is added to an aqueous solution of cobalt(nitrate, Co(NO3)2. Give the formulae and geometry of the complexes formed. There are two isomers with the formula Ni(R3P)2I2, but only one structure with the formula Co(R3P)2I2. (R = alkyl, R3P is a monodentate ligand) Draw diagrams showing the structure of Co(R3P)2I2 and the two isomers of Ni(R3P)2I2. Ni(R3P)2I2 Ni(R3P)2I2 Co(R3P)2I2
