Bonding Quiz 19

Why is a Lithium (Li) ion attracted to a Chlorine (Cl) ion but NOT to a Calcium (Ca) ion?

^{Hint: Your periodic table can help you answer this question.}

• Li⁺ will be attracted to Cl^- but NOT to Ca²⁺ because only oppositely charged ions attract each other.

• Li^- will be attracted to Cl⁺ but NOT to Ca^2- because only oppositely charged ions attract each other.

• Li⁺ will be attracted to Cl⁺ but NOT to Ca^2- because only oppositely charged ions attract each other.

In an ionic bond between a metal and a nonmetal, what happens to the valence electrons?
