Answer: Alkali metals have only one valence electron per metal atom. In what ways do physical and chemical properties... Is this a Metal, Nonmetal, or Metalloid? Valence electrons are the sum total of all the electrons in the highest energy level (principal quantum number n). If this were to happen, then the s-orbital of the alkali metal will hybridize with an orbital from the bonded atom to form 2 molecular orbitals: one that is bonding (has significant electron density between both atoms) and one that is anti-bonding. The metals are generally highly reactive and must be kept under oil to avoid any reaction is water and/or air (oxygen). The general form for the electron configuration of each alkali metal is ns 1, where the n refers to the highest occupied principal energy level. Recall that such electrons are called valence electrons. Copyright © 2021 Multiply Media, LLC. Why don't libraries smell like bookstores?
