  16. Multiple Choice 18 • How many electrons does potassium need to gain or lose to become stable? • Gain 1 • Gain 2 • Lose 1 • Lose 2 How many valence electrons does potassium have?

  17. Multiple Choice 18 • How many electrons does potassium need to gain or lose to become stable? • Gain 1 • Gain 2 • Lose 1 • Lose 2 How many valence electrons does potassium have? 1 valence, so only needs to LOSE 1.

  18. Multiple Choice 20 • How many single, double, and triple bonds does it have? • 10 single bonds, 0 double bonds, & 0 triple bonds • 8 single bonds, 1 double bond, & 0 triple bonds • 1 single bond, 8 double bonds, & 0 triple bonds • 0 single bonds, 0 double bonds, & 10 triple bonds

  19. Single Bonds Double Bonds

  20. Single Bonds - 8 Double Bonds - 1

  22. Short Answer: 8 valence • Predict whether an element with a valence of 8 is most likely form ionic bonds, covalent bonds, or no chemical bonds with other atoms. Explain.

  23. Short Answer: 8 valence • Predict whether an element with a valence of 8 is most likely form ionic bonds, covalent bonds, or no chemical bonds with other atoms. Explain. 3 points: • 8 valence = • 8 valence = • Therefore…

  24. Short Answer: 8 valence • Predict whether an element with a valence of 8 is most likely form ionic bonds, covalent bonds, or no chemical bonds with other atoms. Explain. 3 points: • 8 valence = Noble Gas • 8 valence = stable • Therefore, not likely to form bonds

  25. Short Answer: 7 valence • Draw the Lewis dot structure of Chlorine (Cl) [or Fluorine (F). Propose an explanation for why it does not form double bonds.

  26. Short Answer: 7 valence • Draw the Lewis dot structure of Chlorine (Cl) [or Fluorine (F). Propose an explanation for why it does not form double bonds. 4 points: • Drawing: seven valence = seven dots • Only 1 lonely electron • Therefore only 1 bond needed

  27. Short Answer: 7 valence • Draw the Lewis dot structure of Chlorine (Cl) [or Fluorine (F). Propose an explanation for why it does not form double bonds. 4 points: • Drawing: seven valence = seven dots • Only 1 lonely electron • Therefore only 1 bond needed • Most likely going to form ionic bonds Bonus Point!
