What are Ionic Bonds?

Ionic bonds are a type of chemical bond that forms between two atoms with a significant difference in their electronegativity values. This difference in electronegativity leads to the transfer of electrons from one atom to another, resulting in the formation of ions with opposite charges. The electrostatic attraction between these oppositely charged ions holds them together, forming a strong and stable bond.

Key Characteristics of Ionic Bonds

To determine whether a pair of elements will form an ionic bond, we need to consider the following key characteristics:

Electronegativity: The ability of an atom to attract electrons towards itself. Atoms with high electronegativity values tend to attract electrons more strongly.
Electron transfer: The transfer of electrons from one atom to another, resulting in the formation of ions with opposite charges.
Charge balance: The electrostatic attraction between oppositely charged ions holds them together, forming a strong and stable bond.

Analyzing the Options

Now, let's analyze the given options to determine which pair of elements will form an ionic bond.

Option A: N and O

Nitrogen (N) and Oxygen (O) are both nonmetals with relatively high electronegativity values. However, the difference in their electronegativity values is not significant enough to result in the transfer of electrons. As a result, N and O will not form an ionic bond.

Option B: K and Br

Potassium (K) is a metal with a low electronegativity value, while Bromine (Br) is a nonmetal with a high electronegativity value. The significant difference in their electronegativity values will result in the transfer of electrons from K to Br, forming ions with opposite charges. This will lead to the formation of an ionic bond between K and Br.

Option C: C and Cl

Carbon (C) is a nonmetal with a relatively low electronegativity value, while Chlorine (Cl) is a nonmetal with a high electronegativity value. However, the difference in their electronegativity values is not significant enough to result in the transfer of electrons. As a result, C and Cl will not form an ionic bond.

Option D: Fe and Ni

Iron (Fe) and Nickel (Ni) are both metals with relatively low electronegativity values. The difference in their electronegativity values is not significant enough to result in the transfer of electrons. As a result, Fe and Ni will not form an ionic bond.

Conclusion

Based on the analysis of the given options, the pair of elements that will form an ionic bond is B. K and Br. The significant difference in the electronegativity values of K and Br will result in the transfer of electrons from K to Br, forming ions with opposite charges and leading to the formation of an ionic bond.

Key Takeaways
