Question

a solid is held together with intermolecular forces and has a dull appearance. it has the particle model shown. what type of solid is it? network ionic metallic molecular

Explanation:

The solid is held by intermolecular forces (not covalent/ionic bonds or metallic bonding) and has a dull appearance. Molecular solids consist of discrete molecules held by intermolecular forces and typically have dull surfaces. Network solids use covalent bonds, ionic solids use ionic bonds, and metallic solids use metallic bonding—none match the given description.

Answer:

molecular
