Question

What is the general outermost shell electronic configuration for Lanthanoids?

Answer 1

Lanthanoids:

• The lanthanoid series consists of metallic elements from atomic number $57\mathrm{to}71$.
• They are considered f-block transition metals.
• These elements are placed separately in the periodic table due to their different electronic structures.

General electronic configuration for Lanthanoids:

• The general outermost shell electronic configuration for Lanthanoids is $(\mathrm{n}-2){\mathrm{f}}^{1-14}(\mathrm{n}-1){\mathrm{d}}^{0-1}{\mathrm{ns}}^2$.
