Chapter Sixteen: Compounds 16.1 Chemical Bonds 16.2 Chemical Formulas 16.3 Molecules CHEMICAL BONDING Occurs when 2 or more atoms combine Can be from the same element (O2) or different elements (NaCl) Atoms combine so that they each have a total of 8 valence electrons (full octet) 16.1 Valence electrons Chemical bonds are formed only between the electrons in the highest unfilled energy level. These electrons are called valence electrons. 16.1 Valence electrons and the periodic table Going from left to right across a period each new element has one more valence electron than the one before it (A group). How many valence electrons does nitrogen have? 16.1 Lewis dot diagrams A clever way to keep track of valence electrons is to draw Lewis dot diagrams. A dot diagram shows the element symbol surrounded by one to eight dots representing the What is the dot valence electrons. structure for nitrogen?
