Ionic Compounds
An ionic compound is a bonded pair of metal and nonmetal components that could be elements and or polyatomics (bonded elements/atoms).
To determine if a component is metal or nonmetal is by their charge: metals have a positive charge while nonmetals have a negative one.
The most common polyatomics usually have a negative charge.
For example,
- Sodium Nitrate, [tex]\rm Na(NO_3)[/tex]: Na has a positive charge and the polyatomic [tex]\rm NO_3[/tex] has a negative charge;
- Lithium Oxide, [tex]\rm LiO[/tex]: Li has a positive charge and O has a negative charge.

Solving the Problem
It asks for which isn't an ionic compound, so we must find a compound who has either two negative or two positive charges.
Answer choice A has the components Na and F, both are a metal and nonmetal element respectively. Thus, A is ionic and can be eliminated.
Answer choice B has the components Na, which has a positive charge, and OH, which has a negative charge. Thus, B is also ionic and can be eliminated.
Answer choice C has the components F and [tex]\rm Cl_3[/tex], both are nonmetals that have negative charges. Thus, C isn't ionic and can be our final answer.
Let's keep going to make sure C is the correct answer.
Answer choices D and E have metal and nonmetal elements respectively. Thus, D and E can be eliminated.
So,
C is our final answer!
The compound (c) FCl₃ is not an ionic compound.
To determine which compound is not an ionic compound among the given options, we need to inspect the nature of the bonds between their constituent atoms:
- NaF – This compound is ionic because it consists of sodium (Na) and fluorine (F), a metal and a nonmetal respectively.
- NaOH – This is also an ionic compound since it contains sodium (Na), a metal, bonded to hydroxide (OH), a polyatomic ion.
- FCl₃ – This is not an ionic compound. It consists of fluorine (F) and chlorine (Cl), both of which are nonmetals, forming a covalent bond.
- CaO – This compound is ionic as it consists of calcium (Ca), a metal, and oxygen (O), a nonmetal.
- MgCl₂ – This is an ionic compound composed of magnesium (Mg), a metal, and chlorine (Cl), a nonmetal.
Among the given compounds, FCl₃ is the one that is not an ionic compound.
The correct question is shown below:
Which of the following is not an ionic compound?
a. NaF
b. NaOH
c. FCl₃
d. CaO
e. MgCl₂
