WebbEach hydrogen atom has one valence electron and is univalent. 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 ... Webb6 mars 2024 · Valence electrons are the electrons contained in the outermost shell. If you look at the periodic table and at the period numbers, that is the number of valence electrons. If the number is larger than 10, subtract 10 so you get two valence electrons. Example: Oxygen is in the 16th period.
