Explain. 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… 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 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. 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 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: Bonus Point! Drawing: seven valence = seven dots Only 1 lonely electron Therefore only 1 bond needed Most likely going to form ionic bonds
