Electronic configuration of Lanthanium:

A. A. [Xe]625d

1s22s22p63s23p63d104s24p64d105s25p6 5d16s2

Xe 5d16S2

Step-by-step explanation:

Lanthanium has atomic number of 57 and symbol La. It is in group 3 and period 6 of the periodic table.

Due to presence of electron in their d-sebshell, Lanthanium is a d-block element. Two isotopes of lanthanium is found.

Lanthium is a element of lanthanide series

Electron in each shell is 2,8,18,18,9,2

The electronic configuration of La is
