Chemical Bonds Review

LiF is an example of a -

• ionic bond

• covalent bond

• metallic bond

Correctly identify the cation and anion in the compound Sodium Chloride, NaCl.

• chlorine is the anion because it is a negative metal; chlorine is a cation because it is a positive nonmetal.

• sodium is a cation because it is a positive metal; chlorine is a anion because it is a negative nonmetal.

Noble gases are incapable (not able to) of forming bonds. WHY?

• high electronegativity

• full valence shell (8)

• high atomic radii

• empty valence shell (0)
