What is a Solid? Part 2 – Crystals and Amorphous Solids

Solids are made up of several different types of molecules and are classified according to their microscopic structure. Platonic, amorphous, and crystalline solids are discussed here. The next part of this article explains the difference between crystals and amorphous solids. If you haven’t figured out what each type of solid is, then read on! – What is a solid? – What is its chemical makeup?

Platonic solids

Platonic solids are convex regular polyhedra in three-dimensional Euclidean space. Regular polyhedra are shapes in which the same number of faces meet at every vertex. However, there are many kinds of Platonic solids. Here are some of the most common types. In general, a Platonic solid has five faces. This article will focus on four of the most common types. But, for a deeper understanding, let’s first define a few of these.

Crystalline solids

Crystalline solids are collections of atoms and molecules held together by chemical bonds. These solids can be divided into four different types: metallic, ionic, and molecular. The properties of each type of crystal are described in the table below. Let’s look at examples of each of these types of crystals. Let’s start with sodium chloride, which is a perfect example of a crystalline solid. Its crystal structure contains equal numbers of sodium and chloride ions, and it is composed of a ring of six sodium ions surrounding a ring of six chloride ions. It is the simplest crystalline structure known.

Amorphous solids

Amorphous solids are non-crystalline substances, lacking long-range order. Their properties have long been important for pharmaceutical research, and recent interest in glass science has increased the focus on these materials. The most important properties of amorphous solids are their apparent glass transition temperature and crystalline melting point. The latter is an important parameter for evaluating the stability and suitability of pharmaceutical dosage forms. Here are some properties of amorphous solids and their applications.


The study of solids encompasses all the elements that make up a crystal, including its structure, properties, and properties. Solids are composed of atoms and molecules, which are arranged in planes that are parallel to each other. In addition, solids are made up of unit cells, or space lattices. These small pieces of matter are linked together by a regular arrangement that mirrors the internal symmetry of the crystal.

Covalent-network solids

A network solid is a chemical compound where atoms are joined together in a continuous network of covalent bonds. Since there are no individual molecules within a network solid, the entire compound is considered a macromolecule. Here is an overview of covalent-network solids. Let’s begin with what network solids are and what makes them unique. Graphene is a popular example. It is a solid composed entirely of atoms and may even be considered a macromolecule.
