Answer 1

C. Fluorine (F) is most likely to form a molecule with sodium that includes one ionic bond. Fluorine is a highly reactive nonmetal, and it tends to gain one electron to form a fluoride ion (F-). Sodium is a highly reactive metal that tends to lose one electron to form a sodium ion (Na+). When these two elements react, they form an ionic compound, sodium fluoride (NaF), which includes one ionic bond between Na+ and F-.
