Questions & Step-by-Step Solutions

In a coordination compound, what does the term 'coordination number' refer to?
  • Step 1: Understand what a coordination compound is. It is a complex made of a central metal ion and surrounding molecules or ions called ligands.
  • Step 2: Identify the central metal ion in the coordination compound. This is the main atom that is surrounded by ligands.
  • Step 3: Count the number of ligands that are directly attached to the central metal ion. These ligands can be molecules or ions.
  • Step 4: The total number of these ligands is called the coordination number.
