Answer: how the atomic scale structure of solids explains their large-scale properties
Explanation:
Solid state physics is a branch of physics (specifically condensed matter) that studies solids (rigid or semi-rigid matter), through its atomic description.
Then, it can be said that it studies the properties the solids present when they are gathered in a remarkable number of atoms.
This means, solid state physics fundamentally studies the properties due to the periodic ordering of the atoms in a solid.
