Verified step by step guidance1
Understand the nature of ionic compounds: Ionic compounds typically form between metals and nonmetals, where one atom donates electrons (forming a cation) and the other accepts electrons (forming an anion).
Identify the elements given: Carbon, Nitrogen, and Oxygen are nonmetals, while Sodium is a metal.
Recall that fluorine is a highly electronegative nonmetal that tends to gain electrons and form anions (F⁻).
Since ionic bonds form between metals and nonmetals, the element that is a metal (Sodium) will lose electrons to fluorine, resulting in an ionic bond.
Therefore, Sodium combined with fluorine will most likely form an ionic compound, while the other nonmetals tend to form covalent bonds with fluorine.
