Which is classified as an inner transition element? a) calcium
2020年9月11日 · Fermium is classified as an inner transition element. Explanation: The inner transition elements are a group of elements that occupy the f-block of the periodic table. They are characterized by their electron configurations that involve filling the f-orbitals. Calcium, copper, and helium do not belong in this group.
Which element is only made in the laboratory? A. Cerium
3. **Fermium (C)**: This element is a synthetic element, which means it is not found naturally and was first created in a laboratory setting during nuclear reactions. 4. **Neodymium (D)**: Like cerium and thorium, neodymium is also a rare earth element that occurs naturally and can be mined. From this breakdown, the correct answer is **C ...
