What is the coordination number of the complex ion [Co(NH3)6]3+?
Step 1: Identify the complex ion, which is [Co(NH3)6]3+. This means we have a cobalt ion (Co) surrounded by ligands.
Step 2: Look at the ligands attached to the cobalt ion. In this case, the ligand is NH3 (ammonia).
Step 3: Count the number of ammonia ligands. There are 6 ammonia ligands in the formula.
Step 4: The coordination number is defined as the number of ligands attached to the central metal ion. Since there are 6 ammonia ligands, the coordination number is 6.
