WebbThe presence of valence electrons can determine the element's chemical properties and whether it may bond with other elements: For a main group element, a valence electron can only be in the outermost electron shell. An atom with a closed shell of valence electrons (corresponding to an electron configuration s p ) tends to be chemically inert. 2 6 Webb7 apr. 2024 · The state-of-the-art defect engineering techniques have paved the way to realize novel quantum phases out of pristine materials.
