The Total solution for NCERT class 6-12
What are the characteristics ofthe transition elements and why are they called transition elements? Whichof the d-block elements may not be regarded as the transitionelements?
Transition elements are thoseelements in which the atoms or ions (in stable oxidation state) containpartially filled d-orbital. These elements lie in the d-blockand show a transition of properties between s-block and p-block.Therefore, these are called transition elements.
Elements such as Zn, Cd, and Hgcannot be classified as transition elements because these have completelyfilled d-subshell.
