Correct answer: D. Crab claws
- A. Bidentate
- B. lon
- C. Monodentate
- D. Crab claws
- E. Metal
Explanation
Chelates are sometimes metaphorically referred to as "crab claws" because of how they "grasp" a metal ion with multiple coordination sites, similar to how a crab uses its claws to hold onto something.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
