Questions & Step-by-Step Solutions
What is the coordination number of the complex ion [Cu(NH3)4]2+?
Step 1: Identify the complex ion, which is [Cu(NH3)4]2+. This means we have a copper ion (Cu) and four ammonia molecules (NH3).
Step 2: Understand what a coordination number is. The coordination number is the number of ligands (molecules or ions that are bonded to the central metal ion) attached to the central metal ion.
Step 3: Count the number of ammonia ligands in the complex. In [Cu(NH3)4]2+, there are four ammonia ligands.
Step 4: Conclude that the coordination number is equal to the number of ligands. Since there are four ammonia ligands, the coordination number is 4.
