d block elements note
Understand the Problem
The question is asking for notes or information about d block elements, which typically refers to the transition metals in the periodic table. These elements have their outermost electrons in d orbitals, and the question likely seeks a summary or detailed notes on their properties, uses, and characteristics.
Answer
The d-block includes elements from Groups 3 to 12, starting with Scandium (Sc) up to Mercury (Hg).
The d-block elements span Groups 3 to 12 in the periodic table. They start from Scandium (Sc) and Zinc (Zn) in the 3d subshell, continue with Yttrium (Y) to Cadmium (Cd) in the 4d subshell, and include Hafnium (Hf) to Mercury (Hg) in the 5d subshell.

More Information
The d-block elements are often referred to as transition metals and are known for their ability to form compounds with a wide range of oxidation states and complex ions.
Tips
A common mistake is confusing the boundary of the d-block with other blocks, always check the periodic table to confirm.
