In chemistry and physics, a valence electron is an electron in the outer shell associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed. In a single covalent bond, a shared pair forms with both atoms in the bond each contributing one valence electron. The presence of valence electrons can determine the element's chemical proper… WebOct 11, 2024 · As the outermost shell have only one electron and the atom of an element having less than four electrons in the valence shell is called conductor. Al = 13: As the outermost shell consists of 3 electrons and we know that the atom of an element having less than four electrons are called conductor. So, Al is an conductor. Na: Atom number is …

WebElectrons in the outermost shell (valence electrons) are more shielded and farther from the nucleus on average, so they have the lowest binding energies of all of the electrons in an atom. In contrast, electrons in inner shells (core electrons) are less shielded and closer to the nucleus on average, so they have higher binding energies. robbin crosby
