They are called the Halogens. They are group 17 on the periodic table. Flourine is a common example of such gas.
Group 8A elements (Noble Gases) are unreactive elements known for their stable electron configurations. Transition metals are elements found in Groups 3-12 of the periodic table and are known for their variable oxidation states and ability to form colorful compounds.
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.
Xenon belongs to the noble gases group in the periodic table.
it is 35
Argon is found in the group of noble gases.
Halogens, Group 7.
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.
Group 2, or the alkaline earth metals.
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 8A elements (Noble Gases) are unreactive elements known for their stable electron configurations. Transition metals are elements found in Groups 3-12 of the periodic table and are known for their variable oxidation states and ability to form colorful compounds.
Noble gases.
The grup 8 elemnts are quite unreactive- the term noble was I think coined for gold and other unreactive metals- and the adjective got re-used- they were once called the inert gases- but this is no longer true as unstable reactive compounds have been made for Argon and the heavier members of the group.
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.
Helium is a Noble Gas in Group O.
Xenon belongs to the noble gases group in the periodic table.
