Name: Steps for drawing an ionic bond 1. Determine the number of valence electrons for each element. 2. Decide which element is the nonmetal and draw the Lewis dot structure for this element (Element #1) in the center. 3. Create a bond for each unpaired electron in Element #1 by: a. Drawing the Lewis dot Structure for the metal (Element #2) next to each unpaired electron b. Draw an arrow to show that the electrons will be transferred from Element #2 to Element #1 4. Continue adding bonds until Element i#1 has a full outer sheil and Element #2 has no valence electrons left. Example (Lithium and nitrogen) 1. Lithium 1 valence electron Nitrogen 5 valence electrons 2. Lithium is a metal and nitrogen is a nonmetal. ON 8 3. Lie Li 4. Li Li ON8 Q L 8N8 Li Practice: 1. Draw the following ionic compounds 2. Write the compound's name 3. Write the compound's formula 1. Sodium + Bromine Na Br: 2. Magnesium + Chlorine Mg 10 name: CoBodium Bromide Formula: NaBr Compound name: Magnesium Chloride Formula: MgCl2 3. Lithium + Oxygen Li ): Lio Compound name; Lithium Oxide Formula: Liz0 4. Aluminum + Fluorine Al. F: F: Compound name: Aluminum fluoride Formula: AlF3- 5. Beryllium + Nitrogen 0 BeN → 0 be Compound name: Nitride Formula: Bez Na A
