What are d-block and f-block elements?
The d-block elements are called transition metals and have valence electrons in d orbital’s. The f-block elements,found in the two rows at the bottom of the periodic table, are called inner transition metals and have valence electrons in the f-orbital’s.
What is D and f-block?
The d-block of the periodic table contains the elements of the groups 3-12 in which the d orbitals are progressively filled in each of the four long periods. The f-block consists of elements in which 4 f and 5 f orbitals are progressively filled. They are placed in a separate panel at the bottom of the periodic table.
Why D and f-block elements are called transition elements?
The d-block elements are called transition elements because they exhibit transitional behaviour between s-block and p-block elements. Their properties are transitional between highly reactive metallic elements of s-block which are ionic in nature and the elements of p-block which are covalent in nature.
What is f-block element?
What are F Block Elements? Elements whose f orbital getting filled up by electrons are called f block elements. These elements have electrons, (1 to 14) in the f orbital, (0 to 1) in the d orbital of the penultimate energy level and in the outermost’s orbital.
What group are f-block elements?
3rd group
The group of f-block elements is IIIB or 3rd group.

What is the importance of the D and f block elements?
The d and f block elements introduce various important topics to the students like general properties of the transition elements (d block), physical properties, variation in atomic and ionic sizes of transition metals, ionization enthalpies, oxidation states, magnetic properties, the formation of coloured ions and complex compounds.
What are D-Block and f-block elements?
The d-block (groups 3-12) and f-block elements are also called transition and inner transition elements respectively. All d & f-block elements are metals. Download NCERT Class 12 Chemistry Solutions Chapter 8 d and f Block Elements in PDF format by visiting BYJU’S
