What is the EAN of nickel in

{\left[ {\mathrm{Ni}{{\left( {\mathrm{CN}} \right)}_4}} \right]^{2 - }}?

View answer and explanation

Correct option: C

Option C (34) is correct because the Effective Atomic Number (EAN) is calculated by subtracting the oxidation state of the metal from its atomic number and adding twice the coordination number.
