As shown in , the group 18 atoms helium (He), neon (Ne), and argon (Ar) all have filled outer electron shells, making it unnecessary for them to gain or lose electrons to attain stability; they are highly stable as single atoms. Their non-reactivity has resulted in their being named the inert gases (or noble gases).Click to see full answer. In this manner, which element had complete outer shell? noble gases Beside above, what is the name of the family of elements that has a full outer shell of electrons? The noble gases are a group of elements in the periodic table. They are located to the far right of the periodic table and make up the eighteenth column. Elements in the noble gas family have atoms with a full outer shell of electrons. They are also called the inert gases. Additionally, what term is used for the electrons in the outermost shell? Explanation: The outermost shell is known as the “valence shell”. Therefore, the electrons in the outermost shell are known as “valence electrons”.Which element would be most likely to gain electrons?Nonmetals (the right 1/3 of the Chart) when they form ionic compounds do so by gaining electrons. This due to the fact that they have high ionization energies and high electron affinities (referring to their ability to collect electrons). When they do form ions, they are of negative charge and are called anions.
