The state of aggregation of solids can be described as belonging to the following four types: ionic, metallic, covalent network, and molecular. For each of these types of solids, indicate the kinds of particles that occupy the lattice points and identify forces among the particles. How could each type of solid be identified in the laboratory.
I suggest you make a table and write the properties of each kind of aggregate state. That will tell you how they might be identified in the laboratory as well as the forces between those particles. I'm not sure what the problem is asking with regard to the kinds of particles that occupy the lattice points unless the question means ion, or atom.
