Question

what is the coordination number in complex compounds ​

Answer 1

Answer:

In coordination chemistry, the coordination number is the number of ligands attached to the central ion (more specifically, the number of donor atoms). Coordination numbers are normally between two and nine. The number of bonds depends on the size, charge, and electron configuration of the metal ion and the ligands.

Answer 2

Explanation:

The net residing on the complex ion is it's charge number .It is algebric sum of the charges

carried by the metal ion and the ligands.

e.g. the complex Fe(CN)6]⁴has charge number of -4.
