#ExplanationThe periodic table of elements is organized into groups (vertical columns) and periods (horizontal rows). Each group has specific characteristics and properties. Group 17, for instance, is known as the halogens. Halogens are nonmetals and they are characterized by their high reactivity, especially with metals to form salts.Noble gases are located in group 18, not group 17. They are known for their low reactivity due to their full valence electron shells. Metals, on the other hand, are typically located on the left side of the periodic table and have properties such as malleability, ductility, and good conductivity of heat and electricity. These properties are not characteristic of the elements in group 17.#AnswerB The elements in group 17 are both halogens and nonmetals.
