Following property of transition elements does not vary with a regular pattern:
Correct answer: D. Cationic radius
- A. Binding energy
- B. Covalent radius
- C. Melting point
- D. Cationic radius
Explanation
The cationic radius of transition elements does not vary with a regular pattern because the number of electrons in the outermost shell (valence electrons) affects the effective nuclear charge experienced by the remaining electrons, leading to variations in the ionic radius. Additionally, the presence of partially filled d orbitals in transition metals can lead to complex electron-electron repulsion effects, further influencing the cationic radius.

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.
