WebIn the compound Ni (CO)4, the primary valency of Ni is +2. This is because Ni (CO)4 is a neutral molecule, and each CO molecule has a neutral charge. Since there are four CO molecules bound to the Ni atom, which are considered as ligands, they will each donate a lone pair of electrons to the Ni atom to form a coordination complex.
