Question

examples of f-block element??​

Answer 1

The f block elements are the lanthanides and actinides and are called the inner transition elements because of their placement in the periodic table due to their electron configurations. The f orbitals of the electron shell are filled with “n-2.” There is a maximum of fourteen electrons that can occupy the f orbitals.

Answer 2

Hi......

f - block is an extension of the d- block.

d-block elements are called as transition elements also.

so, as the f -block is an extension of the d-block ,the elements of f-block are also called are inner-transition elements.

The elements of the f-block are as follows:-

(from atomic number 57 to 103 elements)

1. Lanthanum
2. Cerium
3. Praseodymium
4. Neodymium
5. Promethium
6. Samarium
7. Europium
8. Gadolinium
9. Terbium
10. Dysprosium
11. Holmium
12. Erbium
13. Thulium
14. Ytterbium
15. Lutetium
16. Actinium
17. Thorium
18. Protactitium
19. Uranium
20. Neptunium
21. Plutonium
22. Americium
23. Curium
24. Berkelium
25. Californium
26. Einstenium
27. Fermium
28. Mendelivium
29. Nobelium
30. Lawrencium.

Hope it helps......
