For instance, the right column is occupied by the noble gases. Because they have an outer shell of electrons that is completely filled, they are inert in behavior. (See the article atomic orbital for a more detailed explanation of the building up of the electronic shells.) On the extreme left there is a group of metals, called the alkali metals. One example of how we did this was by placing ITSM vendors such as ServiceNow, BMC, Solarwinds, Cherwell, and Ivanti in the Noble Gases. Their respective suites, and the individual tools of which they are composed, could easily have dominated the entire periodic table.

Group 18 of the modern periodic table consists of noble gases. Helium, neon, argon, krypton, xenon, and radon are noble gases. These gases are monoatomic and chemically inert under normal conditions and hence are also named as inert gases. These gases are present in very small quantities in the atmosphere, and so they are also called rare gases.

Position of isotopes :- Isotopes of an element have different atomic masses , so they must be given . different position in Mendeleev s periodic table but it is not so . Position of Noble Gases in the Periodic Table: Due to their approximately inert chemical nature, the noble-gases occupy a peculiar place in the chemistry. Mendeleev had not left any vacant spaces for the noble gases in his periodic table however he had left such spaces for some other elements that were not known at that time. The noble gases (He, Ne, Ar, etc.) are all in the right-most column of the periodic table. Their ground state configurations have no partially filled subshells; having a complete subshell is favorable from the standpoint of minimizing energy so these elements do not react readily.

The six noble gases are found in group 18 of the periodic table. These elements were considered to be inert gases until the 1960's, because their oxidation number of 0 prevents the noble gases from forming compounds readily.
