SUMMARY
The coordination number of metal ions can be determined using various methods, including Molecular Orbital (MO) theory and the Effective Atomic Number (EAN) method. In the case of nickel (Ni) and ammonia (NH3), the coordination number is typically 6, which aligns with the common oxidation states of nickel. While the EAN method provides a useful guideline, it has exceptions that require memorization and practice for accurate application.
