because they have completely filled outer most energy levels
Very much so. The only group that isn't reactive is the Noble gases, however even some noble gases will react under the right conditions.
It is a noble gas; noble gases are chemically inert. Some compounds have been synthesised however.
At room temperature the lighter halogens, F, Cl are diatomic gases, Br is a liquid, I is a solid. All of the halogens are colored and toxic. The noble gases are all colorless odorless non chemically toxic monoatomic gases. (Radon is radioactive).
Halogens can be gaseous, liquid or solid; noble gases are only gases.Halogens are very chemical reactive elements; only some compounds of noble gases are known.

Noble gasses are used to store sample of highly reactive substances such as alkali metals. Noble gasses are also use in "neon" lights, though only some of them actually contain neon.
Noble gases are the group of elements that are very stable and nonreactive due to their full outer electron shells, which gives them little tendency to gain, lose, or share electrons to form chemical bonds.
Gases can be considered non-reactive if they have a full valence shell, meaning they do not readily form bonds with other elements. Noble gases, such as helium, neon, and argon, are prime examples of non-reactive gases due to their stable electron configurations. Additionally, some gases may be non-reactive under certain conditions, such as low temperatures or pressures, where their kinetic energy is insufficient to overcome activation barriers for chemical reactions.
Noble gases are called inert gases because they are the least reactive elements due to their stable electron configuration. They have a full outer electron shell, making them highly stable and unlikely to form chemical bonds with other elements. This inertness gives them low reactivity under normal conditions.
Noble gases are colorless, odorless, and tasteless, making them very stable and unreactive. They are often used in lighting, such as neon signs and neon lights, due to their ability to emit colorful light when excited by electricity.
