At room temperature which one of the following statements is most ...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.Step 1: Determine the valence electrons of carbon and sulfur atoms. The atomic number of carbon is 6. So its total number of electrons is six. The electron configuration of carbon shows that it has four electrons in its last orbit. Valence electrons of carbon. We already know that the electrons in the last orbit of an element are the valence ...These pairs of electrons present between the Carbon (C) and Sulfur (S) atoms form a chemical bond, which bonds the carbon and sulfur atoms with each other in a CS2 molecule.
