Question 1..

How many d electrons are contained in the metal atoms within each complex below?

Give the coordination number of each complex ion and indicate if the complex is polar..

[Ni(CN)5]3- if this is a trigonal bipyramidal complex, speculate on hybridization of the nickel ?

[Fe(NH3)6]2+

K[Au(CO)6]2+

[Pt(NH3)Cl3]1+

Question2..

A particular metal ion octahedral complex had the same numver of unpaired electrons (non-zero) whether the complex uses weak or strong field ligands. List several fourth period transition metal ions that could have this behavior and defend your answer
