The d and f block Elements Class 12 Notes Pdf – NCERT Book

d and f block elements class 12 notes are an important chapter of an inorganic unit of chemistry class 12. As we know, d and f block elements are also known as transition and inner transition elements. In the modern periodic table, There are four types of blocks. The d and f block is 2nd last and last block and the previous blocks are s and p. If you want to more and more about p block elements, you should read our previous article. Now, Come to the point, first of all, we shall learn d block element means transition elements.

What do you mean by d block elements in brief?

Those elements in which electronic configuration is ended with d-sub orbit, that elements are known as d blocks elements. As we know, there are 7 periods and 18 groups in modern periodic tables but 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 groups elements are in d and f block elements. You should know all 10 groups of this block properly in which all elements are metal.

Groups of d and f block elements

Now, we shall learn all groups of d and f block elements one by one. The 3rd group of modern periodic tables is the 1st group of d-block. Scandium is the 1st element of this group. The 4th group of modern periodic tables is the 2nd group of d-block and Titanium is the 1st element of this group.

The 5th group is the 3rd group of d-block and Vanadium is the 1st element of this group. The 6th group is the 4th group of d-block and Chromium is the 1st element of this group. The 7th group is the 5th group of d-block and Manganese is the 1st element of this group.

The 8th group is the 6th group of d-block and Iron is the 1st element of this group. The 9th group is the seventh group of d-block and Cobalt is the 1st element of this group. The 10th group is the eighth group of d-block and Nickel is the 1st element of this group.

The 11th group is the ninth group of d-block and Copper is the 1st element of this group. The 12th group is the tenth group of d-block and Zinc is the 1st element of this group.
