Noble gases
The six noble gases that occur naturally are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).

All the noble elements to the far right of the periodic table have their s and P sublevels in their valence shell filled, hence they are nonreactive.
These elements, known as the alkali metals (group 1A) and alkaline earth metals (group 2A), are those in which the outer-shell s orbitals are being filled. On the right is a block of six columns. These are the elements in which the outermost p orbitals are being filled.
Neon has a filled outermost shell, as it belongs to the noble gas group and contains a full set of valence electrons.
Elements with full s and p orbitals in their highest electron shell are the noble, or inert, gases of the last column on the periodic table: He, Ne, Ar, Kr, Xe, and Rn.
I dont know the awnser to this ask someone eles

By the outermost shell of electrons

Carbon needs to have 8 electron in its outermost shell to have it completely filled, 4 more valence electrons than it has in the neutral for of carbon.
Neon has a filled outermost shell, as it belongs to the noble gas group and contains a full set of valence electrons.
Elements in same period have same shell. The electron enters outermost shell.
The last shell occupied by representative elements typically corresponds to the valence shell, which is the outermost electron shell. Representative elements are found in groups 1, 2, and 13-18 of the periodic table, and the electrons in their outermost shell determine their chemical properties.
they are determined by the outermost shell of electrons
Because their outermost energy level is only partially filled, some elements are highly reactive, I believe.
