The correct Answer is:
To determine how many of the provided elements are inner transition elements, we first need to understand what inner transition elements are. Inner transition elements are those that belong to the f-block of the periodic table, which includes the lanthanides and actinides. Let's analyze each of the given elements one by one: 1. **Sg (Seaborgium)**: This element is a d-block element and is classified as a transition metal. **Not an inner transition element.** 2. **Bk (Berkelium)**: This element is an actinide and belongs to the f-block. **It is an inner transition element.** 3. **Er (Erbium)**: This element is a lanthanide and belongs to the f-block. **It is an inner transition element.** 4. **Fm (Fermium)**: This element is also an actinide and belongs to the f-block. **It is an inner transition element.** 5. **Fe (Iron)**: This element is a d-block element and is classified as a transition metal. **Not an inner transition element.** 6. **Pb (Lead)**: This element is a p-block element. **Not an inner transition element.** 7. **Cr (Chromium)**: This element is a d-block element and is classified as a transition metal. **Not an inner transition element.** 8. **Ca (Calcium)**: This element is an s-block element. **Not an inner transition element.** 9. **Ar (Argon)**: This element is a p-block element. **Not an inner transition element.** 10. **Zr (Zirconium)**: This element is a d-block element and is classified as a transition metal. **Not an inner transition element.** 11. **Ce (Cerium)**: This element is a lanthanide and belongs to the f-block. **It is an inner transition element.** Now, let's summarize the findings: - Inner Transition Elements: Bk, Er, Fm, Ce - Total Inner Transition Elements: 4 Thus, the answer is **4 inner transition elements**.
