Mark the incorrect statement about the general characteristic features of 3d-series of transition metals:
Correct answer: D. Changes in the ionic radii along the series are regular
- A. Binding energy depends on unpaired electrons
- B. M.P and B.Ps show irregular trend in 3d-series
- C. Diamagnetic substances are weekly repelled by the strong magnetic field
- D. Changes in the ionic radii along the series are regular
Explanation
Changes in the ionic radii along the series are much less regular, so that periodic trends in the properties of these ions are difficult to rationalize. The statement is false hence, this option is correct.

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.
