FAQs
1. What is the difference between D and F block elements?
- D block elements are found in groups 3 to 12, while F block elements are located in the 4th and 5th periods.
- D block elements have variable oxidation states and form colored compounds, whereas F block elements are primarily radioactive and have similar properties within each series.
2. Why are D block elements called transition metals?
They exhibit properties that transition between the properties of s-block and p-block elements.
3. What are the common uses of lanthanides and actinides?
Lanthanides are used in magnets, lighting, and ceramics. Actinides are primarily used in nuclear energy and research.
