For nickelocene, [Ni(η⁵-C₅H₅)₂], let x be the atomic number of Ni, y the oxidation number of Ni, and z the number of electrons donated by the two rings (use ionic counting). Find x − y + z.
Answer:
38
Solution:
x = 28 and y = +2 with two C₅H₅⁻ rings. Each ring donates 6 electrons, so z = 12. x − y + z = 28 − 2 + 12 = 38, which exceeds the 36 of krypton.
