A covalent compound is formed by the combination of a nonmetal with a nonmetal. Of the following, circle the covalent compounds. NaCl Mg Li Na SO3 The noble gases are so stable because they have eight valence (outer) electrons. Look at the periodic table and see if you can figure out a quick way of counting to eight when you get to Group 18. If you can figure it out, using that method, how many valence electrons do the following neutral elements have? Se valence electrons  MgBr valence electrons Ne P PC₁₅ S CO₂  valence electrons
