The periodic table, chapter 4 quiz includes organization of the elements, group properties the noble gases are the most unreactive b/c its outermost shell completes the energy level and is stable enough consider two main-group elements. The six noble gases are found in group 18 of the periodic table they are helium, neon, argon, krypton, xenon, and radon in order of increasing atomic weight these elements were considered to be inert gases, as they have a closed-shell configuration, until the 1960's, because their oxidation number of 0 prevents the noble gases from forming. Ununoctium (element 118) is probably the next noble gas after radon because it is the next box down in the same group however it has a half life of 089 ms, after which it decays to ununhexium (element 116) this means its use is probably limited noble gases were discovered by lord rayleigh and sir william ramsay.
Among the characteristics of the most important noble gases are gaseous elements, they do not interact with other elements, they have a full valence layer, they are rare in nature (their presence on earth is low) and they create fluorescence.

Properties and uses of the noble gases the noble gases are all chemically unreactive gases the table describes their main uses the main uses of the noble gases. The noble gases are the chemical elements in group 18 of the periodic table they are the most stable due to having the maximum number of valence electrons their outer shell can hold therefore, they rarely react with other elements since they are already stable other characteristics of the noble gases are that they all conduct electricity. Although different gasses may differ widely in their chemical properties, they share many physical properties characteristics of gases the air we breathe: 78% n 2 (fairly inert) 21% o 2 (reactive) some common gases. Three main characteristics of noble gases are monatomic nature, gaseous state and completely filled octet configuration we know that all elements seek to complete their valence configuration with octet configuration for this they tend to form ionic or covalent bonds with other or same elements and form compounds.

They are called noble gases, because they rarely bond with lesser elements, ie ones with unfilled outer electron shells they aren't called noble because of chemical reasons, like number of valence electrons, it's the result, which makes them. The noble gases the noble gases (inert gases, group 0, group 18 or the helium group) are notoriously unreactive main vessel superfluid helium will flow uphill over the sides of a beaker to move down with gravity empty beaker pressed.
