Question

Write about f block elements.​

Answer 1

Answer:

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.

• They have General Electronic Configuration of $\sf \: (n - 2)f^{1 - 14} (n - 1)d^{0 - 10} \: n{s}^{0 - 2}$
• These are placed on the bottom of the periodic table consists of 2 rows. 1st row is known as Lanthanoids and the 2nd row is known as Actinoids.
• These are known as Inner Transition elements.
• Actinoids are radio active in nature.
