Question

electronic configuration of f block elements

Answer 1

Answer:

The general electronic configuration of f-

block elements is :- (n-2)f^1 -14(n-1) d^0-

1ns^2 ... The lanthanide series includes

ekements from number 58 to 71, which

is 14 elements. The f sub-level contains

seven obitals and each orbital will hold

two electrons.

Answer 2

Explanation:

The general electron configuration of f-block elements is (n-2) f^1-14(n-1)d^0-1ns^2. The block elements are the LANTHANIDES and ACTINIDES, also known as the inner transition elements. They are placed separately below at the bottom the periodic table as an "ISLAND OF ELEMENTS". There are two speculations as to why they are placed where they are, the first being that they have not been completely studied hence the separation and the second reason being that it just looks Aesthetically pleasing to have a more condensed periodic table!

The general electronic configuration of LANTHANIDES is {xe}4f^(1-14)5d^1 6s^2 and for Actinides it is {Rn}5f^(1-14)6d^0-1 7s ^2
