Answer:
Transition elements are regarded
as those elements which possess partially filled penultimate d-subshell in
their ground state or in one of their commonly occurring oxidation states. This
definition does not cover zinc metals, i.e., the elements of group 12 which are
considered as the end members of four d-block series. In each d-block series,
the penultimate d-orbitals are successively filled. The general electronic
configuration of el-block elements is :
\[(n-1){{d}^{1-10}}n{{s}^{0,1or\,2}}\]
Thus, all the transition metals
are d-block elements but all the d-block elements are not transition metals.
