Lewis Dot Structure Practice #2 1. Determine the bond type (I, C, M) between each of the following atoms. Mg and P ______I_____________ Si and O _______C____________ H and P ______C_____________ Cr and F _______I____________ 2. Determine if the following bonds are ionic, polar covalent or nonpolar covalent using ΔEN. A bond is ionic if the ΔEN is above 2.1, a bond is NPC if the ΔEN is below 0.5, and it’s PC if the ΔEN is between 0.5 and 2.1. Ba + S |0.89 – 2.58| = 1.69  PC C + O |2.55 – 3.44| = 0.89  PC H+F |2.10 – 3.98| = 1.88  PC Se + S |2.55 – 2.58| = 0.03  NPC 3. Complete the following chart. Element Total # of electrons # of valence electrons Nitrogen 7 5 Carbon 6 4 Beryllium 4 2 Neon 10 8 Sulfur 16 6 Potassium 15 1 Lewis Dot diagram 4.
