The most likely property that elements in group 18 (or 8A) share is that they have low or no reactivity. Group 18 elements, also known as noble gases, have a full outer electron shell, making them very stable and unlikely to form chemical bonds with other elements. This characteristic makes them highly unreactive under normal conditions.
