Question

1. choose the best answer.

the crystalline lattice structure of ____ compounds gives them the properties of high melting points, brittleness, and strong bonds.
options: metallic, covalent, ionic

Explanation:

Ionic compounds form a crystalline lattice of charged ions held by strong electrostatic attractions. This strong bonding requires high energy to break, leading to high melting points. The rigid lattice makes them brittle, as shifting ions causes repulsion between like charges that breaks the structure. Metallic compounds are malleable, not brittle, and covalent compounds typically have lower melting points.

Answer:

ionic
