Synthetic elements are primarily found in which of the following groups of the periodic table?

• A. Alkali metals
• B. Actinides
• C. Noble gases
• D. Halogens

Answer: (B)

Verified step by step guidance

1. Understand that synthetic elements are those that are not found naturally on Earth and are typically created artificially in laboratories or nuclear reactors.
2. Recall that synthetic elements are usually heavy elements with high atomic numbers, often beyond uranium (atomic number 92).
3. Identify the groups in the periodic table where such heavy, synthetic elements are commonly located. These are primarily the Actinides, which include elements with atomic numbers from 89 to 103.
4. Recognize that Alkali metals, Noble gases, and Halogens mostly consist of naturally occurring elements and do not primarily contain synthetic elements.
5. Conclude that synthetic elements are primarily found in the Actinides group of the periodic table.
