Group 6A is commonly known as which periodic group?

• A. Group 6A
• B. Noble gases
• C. Halogens
• D. Alkali metals

Answer: (A)

This question tests understanding of how groups are labeled in the periodic table and what the label 6A refers to. Group 6A is the column known historically as the oxygen family, or chalcogens, which includes elements like oxygen and sulfur. The choice that names the group exactly as Group 6A matches that same column in the old labeling system, so it’s the best pick because it directly identifies the intended group. Other options point to different families: noble gases are the far-right group, halogens are another adjacent group, and alkali metals are in the first column. In modern naming, this same column is Group 16, the chalcogens or oxygen family.
