What are the characteristic of f-block elements.

1.	What are the characteristic of f-block elements.
Answer» Characteristic of the f-block elements: (i) The f-block elements are metals having high melting and high boiling points. (ii) These elements exhibit variable oxidation states. The most common oxidation state being 3⁺. (iii) These elements form coloured salts. This is because these salts absorb light of certain wavelength from the visible light. (iv) Actinides (5f-series) are radioactive elements.
