Final answer:
The compound most likely to be an ionic compound is bacl₂.
Step-by-step explanation:
Which one of the following is most likely to be an ionic compound?
When predicting whether a compound is ionic or covalent, we can use the periodic table. Ionic compounds are formed from the combination of a metal and a nonmetal. Covalent compounds are formed from the combination of two nonmetals.
In the given options, the compound that is most likely to be an ionic compound is bacl₂. This is because it consists of a metal (Ba) and nonmetal (Cl). Therefore, the correct answer is option c. bacl₂.
