They are called the Halogens. They are group 17 on the periodic table. Flourine is a common example of such gas.
Group 8A, also known as group 18, are very non-reactive. However, they are all gases, not transition metals. Transition metals are the large family of elements in the middle of the table in between groups 2 and 13 (2A and 3A). Group 8A are the noble gases.
Xenon belongs to the noble gases group in the periodic table.
The opposite of an inert gas would be a reactive gas. Inert gases are stable and do not readily react with other elements, while reactive gases are more likely to form chemical bonds with other elements. Examples of reactive gases include oxygen, chlorine, and fluorine.

The halogens are the most reactive nonmetals. They belong to Group 17 on the periodic table.
Noble gases (or group 18 elements)
The alkali metals are the most reactive group of metals on the periodic table. This group includes elements such as lithium, sodium, and potassium, which readily lose their outer electron to form ions in chemical reactions.
These elements are francium and lithium.
Krypton is a part of the family of elements known as the noble gases. They all lack odor and color, and they are barely reactive.
Group 2, or the alkaline earth metals.
Noble gases.
Group 8A, also known as group 18, are very non-reactive. However, they are all gases, not transition metals. Transition metals are the large family of elements in the middle of the table in between groups 2 and 13 (2A and 3A). Group 8A are the noble gases.
