It's called "nukalium family"
The noble gases in Group 18, or sometimes Group 8depending on what type of Periodic Table you are looking at, are viewed as the most unreactive elements in the periodic table. This is because their shells/energy levels/orbitals are filled with electrons and they are stable (not requiring any extra electrons). They most commonly exist as monoatoms (singular atoms i.e. a single He atom is a monoatom). However, some compounds are known that contain the heavier noble gas elements. For example, xenon can form the compound XeF4 (xenon tetrafluoride) which is a stable compound. The reasons for this are quite complex and involve some interesting orbital interactions between the xenon and fluorine atoms.

noble gases are the family that contains element that are highly unreactive
The noble gases (Helium, Neon, Argon, etc)
The Noble gases, Group 8
Group 18 or noble gases.
Noble Gases
It is not true; some metals are not so reactive and noble metals are practically unreactive.
The Noble Gases, group 18
They are all unreactive metals.
The most reactive groups are alkali metals and halogens.
they are so unreactive, they do not need to be extracted from their ore.
metals which dont react with water or acid are called unreactive metals
These metals are members of the family of platinum metals; they are very unreactive, scarce and expensive.
It is not true; some metals are not so reactive and noble metals are practically unreactive.
The Noble Gases, group 18
Alkali metals are very reactive metals.
They are all unreactive metals.
Aluminium is a reactive metal and in nature only the most unreactive metals (such as gold) are found in thir pure form.
unreactive metals, such as gold
Gold, Silver
Electronegativities of metals are very different: alkali metals are very reactive, platinum metals very unreactive. Metals react with nonmetals.

Alkali metals are most reactive metals. Halogen family comprises of highly reactive non-metals.
