What is the hybridization of the central metal ion in [Ni(CO)4]?

What is the hybridization of the central metal ion in [Ni(CO)4]?

Step 1: Identify the central metal ion in the complex [Ni(CO)4]. The central metal ion is nickel (Ni).
Step 2: Determine the oxidation state of nickel in the complex. In [Ni(CO)4], CO is a neutral ligand, so the oxidation state of Ni is 0.
Step 3: Count the number of ligands attached to the nickel ion. There are four CO ligands attached to Ni.
Step 4: Recognize that the coordination number of nickel is 4 because it is surrounded by four ligands.
Step 5: Determine the hybridization based on the coordination number. A coordination number of 4 typically corresponds to sp3 hybridization.
Step 6: Conclude that the hybridization of the central metal ion (Ni) in [Ni(CO)4] is sp3.
