Types of Crystalline Solids

As you all know that there are two types of solids one of which is crystalline solids and the other is amorphous solids. However, solid is also a type of Matter. Crystalline solids are true solids, whereas amorphous solids are not real. You can also call them false solids. There are mainly four types of crystalline solids. These types are such as molecular solids,  ionic solids, metallic solids, and network covalent solids. Apart from this, the classification of Crystalline Solids might be divided on behalf of the nature of intermolecular forces performing on them. As per this, the Crystalline Solids are divided essentially into four types these are Ionic, Covalent, metallic, and molecular solids. You can know in detail about its types from the below. 

Crystalline Solids

A Crystalline Solid is a general type of solid. It is classified into three fundamental dimensional structures. It is made up of constituents or highly regular patterns such as atoms or molecules. Apart from this, it is formed with a crystal lattice. Crystalline solids are dedicated to a real solid, but its solids another type of amorphous solids are not genuine. You can also call them false solids. So this is one of the major solids that are known as crystalline solids. Also, the other structure of molecules and atoms within them can change their appearance and properties. 

Furthermore, you know very well that solid is a form of matter in which the meaning maintains its shape and keeps a consistent volume. So, ahead of further types of solids are crystalline solids, and the other is amorphous solids. However, solid is also a type of Matter. Crystalline solids are actual solids, but amorphous solids are not actual. You can also call them false solids. Despite this, the Crystalline Solids are divided essentially into four types : Ionic, Covalent, metallic, and molecular solids. Below are the following types of Crystalline Solids expressed in brief. You can know all its types and a detailed overview from here. 

Types of Crystalline Solids

The classification of Crystalline Solids might be divided on the behalf of the nature of intermolecular forces performing on them. As per this, the Crystalline Solids are divided essentially into four types these are Ionic, Covalent, metallic, and molecular solids. If you want to know all these types in detail, then follow the points given below.

1. Ionic solid

The Constituents of the Crystalline Solids are positive and negative ions, and it has a strong bond of networks and is arranged systematically. The bonding or force of attraction of the Ionic solid is Coulombic. For instance, NaCl, KCl, CaO, MgO, LiF, ZnS, BaSO4, etc. apart from this, the properties of the Ionic solid is in physical nature, and it is hard and brittle. The melting point of this solid is high (1000 K), and the boiling point is also high (2000 K). It also conducts electricity. 

2. Covalent solid

A covalent solid is also solid. The constituents of the Crystalline Solids are atoms. It is connected in covalent bonds. The bonding of this solid is electron sharing. For example, Quartz, SiC, C (Diamond), C (Graphic), etc. Apart from this, the properties of the Covalent solid are that its physical nature is too hard. The melting point is extremely high (4000 K), and the boiling point is too high (5000 K). They are insulators except for graphite. 

3. Molecular solid 

As the name suggests, it is made up of molecules. Its constituents are polar and no-polar molecules. It’s bonding with molecular interactions (intermolecular forces) and with hydrogen bonding. For instance, Water ice, Solid carbon dioxide, Sucrose, table sugar, Hydrocarbons, Fullerenes, Sulfur, White phosphorus, and Yellow arsenic. The physical nature of this solid is soft. Apart from this, the melting point is low (300 K to 600 K), and the boiling point is (450 K to 800 K). They are insulators. 

4. Metallic Solid 

All the planet’s metals are forms of Metallic Solid. Its constituents are cations in a sea of electrons. The bonding of this metallic solid is metallic. For example, sodium (Na), Au, copper, alloy, gold, zinc, metals, etc. Apart from this, its properties are that its physical nature is ductile malleable.  The melting point of this is high (800 K to 1000 K), and the boiling point is high (1500 K to 2000 K). They are very good conductors with electrical conductivity. 

Conclusion 

Thus, the primary types of crystalline solids are covalent network solids, molecular solids, ionic solids, metallic solids, etc. These are the types of Crystalline Solids. The term Crystalline Solids is specifically a solid material. These constituents are ions, atoms, molecules, etc. These all are the constituents collected in a positively ordered microscopic structure, including a crystal lattice that grows in all orders. Moreover, examples of Crystalline Solids are such as sodium chloride, sodium nitrate, and diamond. It has well-defined edges and faces, tends to have sharp melting points, and diffracts x-rays.
