Question

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

Explanation:

Network solids consist of a continuous, interconnected network of covalently bonded atoms throughout the structure. They are characterized by being brittle, as breaking the solid requires breaking strong covalent bonds across the network. Metallic solids have a sea of delocalized electrons, making them malleable not brittle. Ionic solids have charged ions (not entirely bonded atoms as described) and are brittle but have a different particle structure. Molecular solids are held by weak intermolecular forces, not a full network of bonded atoms.

Answer:

network
