The d-block elements are located in the middle of the periodic table, specifically in Groups 3 to 12. These elements are often referred to as transition metals. D-block elements have their valence electrons in the d-orbital, which gives them unique properties, such as high melting points, the ability to form multiple oxidation states, and the capacity to form complex compounds. They are essential to many industrial processes and have a wide range of applications.
Here’s a breakdown of the d-block elements:
