Tutor, The ultimate solution to the fear of Organic Chemistry, PhD from DRDO in Chemical Science.
Oxidation state of central atom of metal complexs calculateted on the basis of '18 electron rule' viz. after complex formation each central metal contain total no. of 18 valance electrons. For calculation of oxidation state of central metal atom we can follow the following formula
x + nL + Nvse = 18 ( here x = oxidation state of central metal atom, n = total no of like ligand, L = electron contribution, Nvse = no of valence shell electron of the central atom only)
For given problem: x + 4 x 2 + 10 = 18 or x = 0; hence oxidation state of Ni in Ni(CO)4 is 0.
