Question

Does coordination number means the no. Of bonds it can make

Answer 1

No.

Answer 2

Coordination number is defined as the number of ligand donor atoms directly bonded to the central metal atom in a coordination complex, or the number of nearest neighboring ions in an ionic crystal. The phrase "the no. Of bonds it can make" implies the total bonding capacity or potential of an atom, which can be different. For instance, in complexes with metal-metal bonds or bridging ligands, the total number of bonds an atom forms might exceed its coordination number. Therefore, coordination number does not always mean the total number of bonds an atom can make.
