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.
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
