Q: Which of the following elements is a member of the actinide series?
Solution: Plutonium is a member of the actinide series, which includes elements with atomic numbers 89 to 103.
Steps: 4
Step 1: Understand what the actinide series is. It includes elements that have atomic numbers from 89 to 103.
Step 2: Identify the elements in the actinide series. These include elements like actinium (89), thorium (90), uranium (92), neptunium (93), plutonium (94), and others up to lawrencium (103).
Step 3: Check if plutonium is listed among these elements. Plutonium has the atomic number 94.
Step 4: Conclude that since plutonium is within the range of atomic numbers 89 to 103, it is indeed a member of the actinide series.
