In the complex [Ni(CO)4], what is the hybridization of the nickel atom?

In the complex [Ni(CO)4], what is the hybridization of the nickel atom?

Step 1: Identify the central atom in the complex [Ni(CO)4]. The central atom is nickel (Ni).
Step 2: Count the number of ligands attached to the nickel atom. In [Ni(CO)4], there are four CO ligands.
Step 3: Determine the type of bonds formed. Each CO ligand forms a sigma bond with the nickel atom.
Step 4: Since there are four sigma bonds, we need to find the hybridization that corresponds to four bonding regions.
Step 5: The hybridization that corresponds to four bonding regions is sp3 hybridization.
Step 6: Conclude that the hybridization of the nickel atom in [Ni(CO)4] is sp3.
