What are two ways that crystal and molecular structures affect the properties of ionic and covalent compounds?

Answer 1

The cubic shape of sodium chloride crystals is a result of how the ions form crystals.

But Im Still Reading The Rest

Notice how each positive ion is

surrounded by six negative ions, and

each negative ion is surrounded by six

positive ions. This regular arrangement

gives the sodium chloride

crystal its characteristic cubic

shape. You can see this distinctive

crystal shape when you look

at table salt crystals through a

magnifying glass.

Answer 2

Ionic compounds generally have a regular crystal structure. The size, shape, and ratio of the ions in the compound give the crystal its shape. Ionic and covalent compounds have different molecular structures. Both types are organized and have a pattern, giving them the characteristic of breaking, when in contact with force, rather than bending. Covalent compounds can come in individual molecules. The chemical bonds between atoms give a molecule its shape and molecular structure. Molecular structure influences how a substance feels, how well it bonds with other substances, and how our bodies respond to the substance.

Answer 3

Ionic compounds forms large lattices.
