7.2-1 Notes - Multiple BondsJan 31, 2024, 4:57 PM6.2 Ion basicsDirectionsThese guided notes go with this video: https://youtu.be/mhsyzJC7Who(right-click and open in a new tab).All entries (except Personal Notes) will show green check marks when correct.Review & PreviewNo searching! Just think.1. The atoms in ammonium cation () are bonded covalently.However, the group of atoms has lost 1 electron. Why?First, draw the Lewis dot structure for .To make you need to add 1 more H atom.Why do you need to lose 1 electron to do this? Answer below the drawing.2. Why does need to lose 1 electron to add the fourth hydrogen atom?Nitrogen needs to lose an electron to form a bond with hydrogen, otherwise no room to add electronNH41+NH3NH4NH31/5
Learning Success CriteriaI'll know I'm successful when:I can determine the atomic layoutof molecules in Lewis structures.I can draw Lewis structures with multiple bonds.Learn It! #13. Rules for arranging the atoms in a Lewis structure.If you have more than 2 atoms, 1 must be central. Which one?1. hydrogen is NEVER central (only 1 bond). e.g. 2. If carbon is present, it will be central. e.g. 3. Otherwise, choose the first nonhydrogen atom.* e.g. * really the least electronegative element, but this is usually first anyway.4. Personal notes...Learn It! #2Process for drawing Lewis structures5. Write the Lewis dot and structural formulas for: H O2CH Cl3PCl3O22/5
