Answer:
Elements in the Oxygen Group (also called the Chalcogen Group) are all non-metal elements that are located in Group 16 of the periodic table. They include oxygen, sulfur, selenium, tellurium, and polonium. These elements all have similar properties because they have a similar number of valence electrons, which are the electrons in the outermost energy level of an atom. They all also tend to form compounds by gaining two electrons to become negatively charged ions.
