Types of Chemical Bonds Review

Which of the following best describes ionic bonds?

• transfer of electrons between a metal and a metal; resulting in no charges (+/-)

• sharing of electrons between a metal and a nonmetal

• transfer of electrons between a metal and a nonmetal; resulting in ions (charges +/-)

• sharing of electrons between nonmetals

Which of the following best describes covalent bonds?

• transfer of electrons between metal and non metals; resulting in ions (+/-)

• sharing of electrons between atoms (nonmetal + nonmetal)

• transfer of electrons between metal and metal

• sharing of electrons between metal and nonmetal

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)
