Nobel gasses.
This property can be useful in containing substances, like if you want to contain liquid nitrogen you would use an iron container (or practically any other element because nitrogen is almost inert) because the two elements don't interact with each other.
solids
The element family that iron belongs to on the periodic table is the transition metals family. Other elements in this family include cobalt and nickel.
A chemical element is a substance with only one type of atom in it (e.g. only carbon atoms). The known chemical elements are arranged on the Periodic Table of the Elements. Every element has it's own chemical symbol, which is used as a scientific shorthand for quick elemental notation (e.g. Carbon = C, Promethium = Pm).
On the periodic table, there are periods that are rows, and groups that are columns. Elements in the same group react like the other elements in the group.
Neon (Ne) and Helium (He)
Argon is the least likely in the list to react with other elements, because argon is a noble gas and none of the other elements in the list is.
metallic
Helium, neon and argon are the least likely elements to form compounds.
Hydrogen is the least dense of all the elements and all other known substances.
The elements in the family Group 0 - Inert Gases (exc. Radon) will not usually combine with other substances, as this group is highly unreactive. Inert Gases; Helium Neon Argon Krypton Xenon (Radon)
The most reactive elements are alkali metals and halogens.
These are the so-called noble gases.
Group-18 elements least react with other elements. They are inert in nature. They are called noble gases.Elements in group 18 are less likely to react with any other elements. This group is made out of the noble gases. Its members are He, Ne, Ar, Kr, Xe and Rn.
An ELEMENT can not be separated into other elements.
The elements least likely to react with other elements are the noble gases, chemically inert elements in group 8 of the periodic table and so cannot react with other elements. The noble gases are:- Helium Neon Argon Krypton Xenon Radon The metallic elements Gold and Tantalum are also very non reactive but it does react under very high pressure or temperature.
Argon is chemically inert due to the presence of completely filled orbitals. So it is does not react with other elements at STP.
