📘 What Are D and F Block Elements?

D-block elements are called transition metals. They include groups 3 to 12 in the periodic table and show variable oxidation states, colored compounds, and catalytic properties. Examples: Iron (Fe), Copper (Cu), Zinc (Zn).
F-block elements include the lanthanides and actinides. These are known as inner transition metals, often placed separately below the main periodic table. They are known for radioactive behavior (actinides) and magnetic properties (lanthanides).

🧪 What This Quiz Covers:

General properties of d and f block elements
