Strategy:
 The number of coordination sites (denticity) is the number of donor atoms in a single ligand molecule that can bind to a central metal atom.

Step 1: Identify donor atoms in EDTA
 (Ethylenediaminetetraacetate) contains:
- Two Tertiary Nitrogen atoms (from the amine groups).
- Four Oxygen atoms (from the four acetate groups).

Step 2: Sum the sites
Total coordination sites = .
Thus,  is a hexadentate ligand.
