Final answer:
Three physical properties of ionic compounds associated with ionic bonds are high melting and boiling points, hardness, and brittleness.
Step-by-step explanation:
Three physical properties of ionic compounds that are associated with ionic bonds and relate to bond strength are:
- High melting and boiling points: Ionic compounds have strong electrostatic attractions between the positively and negatively charged ions, which require a large amount of energy to break. As a result, they typically have high melting and boiling points.
- Hardness: Ionic compounds are often hard due to the strong bonds holding the ions together.
- Brittleness: Ionic compounds are brittle because when a force is applied, the arrangement of ions in the crystal can shift, causing like-charged ions to come into contact and repel each other, leading to the crystal shattering.
These properties are directly related to the strength of ionic bonds, as the strong electrostatic attractions between the ions result in high melting and boiling points, hardness, and brittleness.
