Elements that have full valence shells
WebMar 2, 2024 · The valence electron exists exclusively in the outermost electron shell of the main group elements. In the inner shell of a transition metal, a valence electron can exist. Chemically, an atom with a closed shell of valence electrons is usually inert. The electrical conductivity of an element is also determined by its valence electrons. WebHelium, neon, and argon are the only elements that have full valence shells. Inert. Helium, neon, and argon. Meaning chemically unreactive.
