Verified step by step guidance1
Understand that the term "halogen characteristics" refers to elements that share similar chemical properties, such as high reactivity and the tendency to gain one electron to form negative ions.
Recall that the periodic table is organized into groups (columns) where elements in the same group have similar properties.
Identify that Group 17 on the periodic table is known as the halogens, which include elements like fluorine, chlorine, bromine, iodine, and astatine.
Recognize that Group 18 contains noble gases, which are generally inert and do not exhibit halogen characteristics.
Conclude that an element with halogen characteristics most likely belongs to Group 17, the halogens.
