The elements which are present between the s and p block elements in the modern periodic table are called the transition elements. 1. D-Block elements consist of element groups 3 to 12 that correspond to the filling of the d-orbital subshell of the second outermost shell. This is because the highest energy subshell (i.e. hopayz33. What groups of elements does block d contain. In this group, the d orbitals are filled progressively. The valence electrons of these elements fall under the d orbital. Within the period density increases because size decreases. Ti - 132 . They are called transition metals because they transition between the highly reactive s block metals and the much less reactive metals of group 12 and the p block.

The general electronic configuration of these elements is (n-1)d1-10ns1-2. The atomic and ionic radii of transition elements are smaller than those of p- block elements and larger than those of s-block elements. Elements having electrons (1 to 10) present in the d-orbital of the penultimate energy level and in the outer most ‘s’ orbital (1-2) are d block elements.Although electrons do not fill up ‘d’ orbital in the group 12 metals, their chemistry is similar in many ways to that of the preceding groups, and so considered as d block elements. There is an approximate correspondence between this nomenclature of blocks, based on electronic configuration, and sets of elements based on chemical properties.The s-block and p-block together are usually considered main-group elements, the d-block corresponds to the transition metals, and the f-block encompasses nearly all of the lanthanides (like lanthanum) and the actinides (like actinium).
