Question

a solid is brittle and has entirely bonded atoms, as seen in the particle model. what type of solid is it? molecular ionic network metallic

Explanation:

The solid is brittle and has a continuous 3D structure of bonded atoms (no discrete molecules). Network solids (e.g., diamond, silica) have such a giant covalent network, are brittle, and lack discrete molecules. Molecular solids have weak intermolecular forces, ionic solids have ions, and metallic solids are malleable—none match the given model’s features.

Answer:

network
