Question

correlation Transition element : d-block : : Inner transition elements : __________________ *​

Answer 1

Explanation:

The elements constituting the f-block are those in which 4f and 5f orbitals are progressively filled. These elements are formal members of group 3 but are shown separately as f-block of the periodic table. The elements of f-block are also called inner transition elements.

The two series of inner transition elements that are 4f and 5f series are known as lanthanoids and actinoids respectively. The inner transition elements such as U, Th and Pa are providing good sources of nuclear energ
