Q: Which of the following transition metals is known for forming a complex with a coordination number of 6?

Solution: Iron (Fe) commonly forms octahedral complexes with a coordination number of 6.

Steps: 5

Step 1: Understand what a transition metal is. Transition metals are elements found in the d-block of the periodic table, known for their ability to form various compounds.
Step 2: Learn about coordination number. The coordination number refers to the number of atoms, ions, or molecules that a central atom or ion can bond with in a complex.
Step 3: Know that a coordination number of 6 typically means the complex has an octahedral shape. This is a common geometry for many transition metal complexes.
Step 4: Identify transition metals that commonly form octahedral complexes. Iron (Fe) is one of the most well-known transition metals that forms such complexes.
Step 5: Conclude that Iron (Fe) is the answer to the question, as it is known for forming complexes with a coordination number of 6.
