d-And f-Block Elements Class 12 Notes

d block elements of the periodic table are present in group 3 to 12 in these elements d orbitals are progressively filled. These are divided into three types of series 3d (Sc- Zn) series, 4d (Y to Cd) series and 5d (La to Hg omitting Ce to Lu). Fourth series of 6d starts with element Actinium (Ac) is still incomplete. These elements are also known as transition elements. f block elements are known as inner transition elements because in these elements the filing of atomic orbitals takes place in subshells i.e. two levels inside the outer subshell. They have been classified in two series i.e. 4f and 5f series.
