The Group 0 elements are called the noble gases. These are the six gases that are almost completely inert. Since they do not lose or gain any electrons, their valence is 0.
mendeleev and others proposed the zero group
Zero group elements are considered monoatomic because they consist of single atoms that do not bond with each other. In a group with zero elements, there are no interactions or combinations possible between atoms, leading to monoatomic nature.
Noble gases were considered elements with zero valency; but today a significant number of noble gases (especially xenon) are known.
Group 1 elements have an oxidation number of +1, group 2 elements have an oxidation number of +2, group 17 elements have an oxidation number of -1, and group 18 elements (noble gases) have zero oxidation number since they are chemically unreactive.
They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with those of other elements to form compounds.
Another name for noble gases is inert gases.
because they have completely filled orbitals (or shells). hence generally are inert
They were once labeled group 0 in the periodic table because it was believed they had a valency of zero, meaning their atoms cannot combine with those of other elements to form compounds.
The noble gases, or group 18 elements, have oxidation states of zero. However, their chemistries are not as barren as one might expect. Please see the link for the periodic table and individual articles for these elements.
Zero group elements are least reactive. Its The Noble Gas Family which is helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).
elements are in the same group since they react similarly to other elements in that group.
