Ionic lattices are typically characterized by:

Ionic lattices are typically characterized by:

• A. High melting points due to strong ionic bonds
• B. Electrical conductivity as solids
• C. Formation from covalent bonds only
• D. Molecules bound by hydrogen bonds

Answer: (A)

The main idea here is how strong the forces are that hold an ionic lattice together. In ionic solids, opposite charges attract each other in a regular three‑dimensional array, so the lattice energy—the energy required to separate the ions—is very large. This makes the solid hard to melt, giving a high melting point because you have to supply a lot of energy to overcome many electrostatic attractions throughout the structure. Because the ions are fixed in place in the solid, ionic solids don’t conduct electricity as solids—the ions can’t move. They only conduct once melted or dissolved, when the ions are free to flow. Ionic lattices aren’t formed by covalent bonds; they’re held together by electrostatic attractions between ions, not by sharing electrons in covalent bonds. And hydrogen bonds bind a different kind of structure known as molecular substances, not typical ionic lattices. So the high melting point reflects the strong electrostatic forces in the lattice, which is the best description of what characterizes ionic lattices.
