Verified step by step guidance
1
Understand that the periodic table is divided into groups (columns) that share similar chemical properties.
Recall that nonmetals are elements that generally lack metallic properties such as conductivity and malleability, and are often found on the right side of the periodic table.
Identify the groups listed: Group 1 (Alkali metals), Group 2 (Alkaline earth metals), Group 17 (Halogens), and Group 18 (Noble gases).
Recognize that Groups 1 and 2 contain metals, so they cannot be groups with only nonmetals.
Focus on Groups 17 and 18, which are known for containing nonmetals; Group 17 contains halogens (nonmetals but also some metalloids), while Group 18 contains noble gases, which are all nonmetals.
