Why the `f`-block elements are called inner transition elements?

Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Understanding the Periodic Table Layout**: The periodic table is organized into blocks based on the electron configuration of the elements. The blocks are designated as s, p, d, and f blocks. 2. **Identifying the f-block Elements**: The f-block elements consist of the lanthanides and actinides. These elements have their last electron entering the f subshell. 3. **Electron Configuration**: For f-block elements, the general electron configuration can be represented as [Xe] 6s² 4fⁿ for lanthanides and [Rn] 7s² 5fⁿ for actinides. This shows that the f subshell is filled after the s and d subshells of the previous periods. ...
