Chapter 5: Problem 2

Which force opposes the interionic forces of attraction between the oppositely charged ions during the formation of an ionic crystal?

Short Answer

Expert verified
Answer: The force that opposes the interionic forces of attraction during the formation of an ionic crystal is the repulsion force between like-charged ions. This force plays a crucial role in maintaining the correct spacing and structure in the crystal lattice, ensuring the stability of the ionic crystal.

Step by step solution

01

Understand interionic forces of attraction in ionic crystals

In an ionic crystal, the interionic forces of attraction are the electrostatic forces between the positively charged cations and negatively charged anions. These forces result in the formation of a regular, repeating arrangement of ions called a crystal lattice, which gives the ionic crystal its stability and unique properties.
02

Identify the force opposing interionic forces of attraction

The force that opposes the interionic forces of attraction during the formation of an ionic crystal is the repulsion force between like-charged ions. While the positively charged cations and negatively charged anions attract each other, the ions of the same charge repel each other.
03

Explain the role of repulsion forces in ionic crystal formation

The repulsion forces between like-charged ions work against the interionic forces of attraction to maintain a balance in the crystal lattice. If the repulsion forces were not present, the interionic forces of attraction would collapse the crystal structure by bringing all the oppositely charged ions close together. The presence of repulsion forces between like-charged ions helps maintain the correct spacing and structure in the crystal lattice, ensuring the stability of the ionic crystal.
