How does the formation of ionic bonds affect the properties of ionic compounds?AThe bonds prevent ions from moving throughout the crystal, so a solid ionic compound is a poor conductor.BThe bonds weakly hold ions together, increasing the melting point.CThe bonds prevent electrons from moving throughout the crystal, so a solid ionic compound is a good conductor.DThe bonds strongly hold ions together, reducing the
Solution
The formation of ionic bonds significantly affects the properties of ionic compounds. Here's how:
A. The bonds prevent ions from moving throughout the crystal, so a solid ionic compound is a poor conductor. This is true. In a solid state, the ions in an ionic compound are held tightly together in a lattice structure and cannot move freely. This makes the compound a poor conductor of electricity. However, when dissolved in water or melted, the ions become free to move and the compound can conduct electricity.
B. The bonds weakly hold ions together, increasing the melting point. This is incorrect. The bonds in an ionic compound are actually quite strong, which gives these compounds high melting and boiling points.
C. The bonds prevent electrons from moving throughout the crystal, so a solid ionic compound is a good conductor. This is incorrect. As mentioned earlier, solid ionic compounds are poor conductors of electricity because the ions are not free to move. It's only when they are dissolved or melted that they can conduct electricity.
D. The bonds strongly hold ions together, reducing the. This statement is incomplete, but the beginning is correct. The strong ionic bonds do hold the ions tightly together in a lattice structure. This gives ionic compounds their characteristic high melting and boiling points, as well as their hardness and brittleness.
