Question

five use of d and f block element​

Answer 1

The d-block of the modern periodic table consists of elements of the groups 3 to 12 in which the orbitals consist of progressively in each of the four long periods. The elements constituting the f – block is those elements in which the 4 f and 5 f are progressively in the later of the two long periods.

These elements are actually formal members of the group three from which they have been taken out to form a separate f – block of the periodic table. The d – block elements acquire the name of transition elements as they represent a significant change in properties from highly electropositive s – block elements to the least electropositive p – block elements.

The transition metals are those elements which have filled incompletely d – subshells in their ground state or in any one of their oxidation state or in any compound form. Cu, Ag and Au are the most common transition metals because, in their commonly occurring states, they have partly filled d – subshells.

Zn, Cd and Hg of group 12 do not have partly filled d – subshell in their elementary state or commonly occurring oxidation state, and hence, are not considered as transition elements. However, being the end members their chemistry becomes understood with transition elements. The Electronic Configuration is ( n-1)d1-10 ns1-2

Answer 2

The d and f block contains both metals and non-metals. The transition elements can be either regular transition elements or the non-typical transition elements. The d – block has three arrangements, each of ten elements. ... Out of these, elements like iron, cobalt and nickel are used in making magnets.
