Chemical Bonds Quiz

Samuel, Avery, and Abigail are studying chemistry together. They learned that the electronegativity of chlorine is 3.16 Paulings. They are now curious to know which element would form ionic bonds if it came into contact with chlorine in a chemical reaction.

• oxygen (3.44 Paulings)

• phosphorus (2.19 Paulings)

• sodium (0.93 Paulings)

• fluorine (3.8 Paulings)
