Introduction

Ionic bonds are a fundamental concept in chemistry, and understanding how they form is crucial for grasping various chemical reactions and processes. In this article, we will delve into the world of ionic bonds, exploring the different ions that can participate in this type of bonding and identifying the combinations that result in an ionic bond.

What are Ionic Bonds?

Ionic bonds are a type of chemical bond that forms between two ions with opposite charges. This bond is typically formed when a metal atom loses one or more electrons to become a positively charged ion (cation), while a non-metal atom gains one or more electrons to become a negatively charged ion (anion). The electrostatic attraction between the oppositely charged ions results in the formation of an ionic bond.

The Ions Involved

Let's take a closer look at the ions listed in the problem:

Na+ (Sodium Ion): A positively charged ion with a +1 charge.
Li+ (Lithium Ion): A positively charged ion with a +1 charge.
O2- (Oxide Ion): A negatively charged ion with a -2 charge.
S2- (Sulfide Ion): A negatively charged ion with a -2 charge.
F- (Fluoride Ion): A negatively charged ion with a -1 charge.

Identifying the Correct Combination

To determine which combination of ions will result in an ionic bond, we need to look for pairs of ions with opposite charges. Let's examine each option:

Option A: NaF

Na+ (Sodium Ion): A positively charged ion with a +1 charge.
F- (Fluoride Ion): A negatively charged ion with a -1 charge.

Since the sodium ion has a +1 charge and the fluoride ion has a -1 charge, they have opposite charges, making this combination a valid candidate for an ionic bond.

Option B: NaO2

Na+ (Sodium Ion): A positively charged ion with a +1 charge.
O2- (Oxide Ion): A negatively charged ion with a -2 charge.

Although the sodium ion has a +1 charge, the oxide ion has a -2 charge, which is not the opposite of +1. Therefore, this combination does not result in an ionic bond.

Option C: LiNa

Li+ (Lithium Ion): A positively charged ion with a +1 charge.
Na+ (Sodium Ion): A positively charged ion with a +1 charge.

Both ions have the same charge, which means they will not form an ionic bond.

Conclusion

In conclusion, the combination of ions that will result in an ionic bond is NaF. This is because the sodium ion (Na+) has a +1 charge, and the fluoride ion (F-) has a -1 charge, making them a pair of ions with opposite charges. Understanding ionic bonds is crucial for grasping various chemical reactions and processes, and identifying the correct combination of ions is essential for predicting the outcome of chemical reactions.
