Carbon facet can type a long chain with itself, i.e., C-C-C-C-C-C… owing to that catenation property i.e., the carbon atom can form a bond with one more carbon atom.

Hence, the carbon atom have the right to exist in various structural forms with various physical and chemical properties. The residential property of the carbon aspect to exist in various structural develops is recognized as Allotropy.

These various structure adjustments are called Allotropes. This allotropes normally exist in the exact same phase. Because that example, all allotropes are present in the solid phase in the case of the carbon atom.

Well, many of the students obtain confused around whether the diamond is an element and compound. So, in this blog, I will cover the difference in between element and compound in recommendation to diamond.

So, Is diamond an element? Yes, Diamond is classified together an element because it is a crystalline type of a solitary element i.e., carbon. The structure of Diamond is cubic type, in which one carbon atom is tetrahedrally bonded to four other carbon atoms. This tetrahedral framework is extended in all three directions. Therefore, it is sometimes referred to as a mineral yet not a compound for sure.

However, Diamond i do not care a link via the introduction of boron and also nitrogen facet as impurities. The impurities impart different colors come the Diamond otherwise the is colorless.

The carbon facet has number of allotropes such together Graphite, Diamond, single-walled carbon nanotubes (CNTs), Buckminsterfullerene (C60), amorphous carbon, C540 fullerite, C70 fullerene, graphene, and Lonsdaleite.

Out of these every allotropes, graphite, diamond, and buckminsterfullerene room the three key allotropes the the carbon atom.

Here, we will emphasis on the diamond, an allotrope of carbon.

Diamond is found naturally in earth’s mantle in ~ the depth of 150-250 km.

However, that can likewise be synthesized one of two people by dealing with the carbon atom under an extremely temperature and pressure or by chemical vapor deposition of hydrocarbons.

So, let us inspect it out in detail. Before that, we should be mindful of the state Atoms, Element, and also Compound i.e., the basic concepts that chemistry.

Atom, Element, and Compound

We all understand that matter exists in three various physical states, namely, solid, liquid, and also gas. However, matter can likewise be classified together a pure substance and a mixture depending upon the chemical nature of constituent particles.

These constituent particles are recognized as Atoms. Atom is the simple unit that Matter, together per Dalton’s theory. Later, scientist realized that atom is composed of subatomic particles, namely, electron, proton, and also neutron.

However, there is a need for atoms to identify the matter based upon their categories. The atoms incorporate to form elements and compounds.

The pure problem is additional categorized right into element and compound ~ above the basis of the type of atoms affiliated in the formation of pure substance.

Elements contain corpuscle of only one kind of atom. They have the right to be atoms or molecules. For example, carbon atom (C), Silicon atom (Si), and argon atom (Ar) room elements.

Similarly, oxygen molecule (O2), nitrogen molecule (N2), and hydrogen molecule (H2) are likewise illustrations that elements.

A compound has particles of more than one type of atom or elements. Carbon dioxide (CO2), water (H2O), and also ammonia (NH3) are some of the examples of the compounds.

Carbon dioxide consists of two elements, which are carbon and also oxygen. Similarly, ammonia and also water additionally contain two species of elements. Hence, all three are thought about compounds.

Now, we can understand whether a Diamond is an facet or a compound.

Why Diamond is Element?

On the communication of the an interpretation of the element and compound, we have the right to say that

Diamond is an facet as it has particles of just one form of atom i.e., the carbon atom. No various other atom is affiliated in Diamond and hence, it can not be a compound.

Diamond is an facet like hydrogen (H2), oxygen (O2), and also nitrogen (N2) space elements.

But, they can be taken into consideration compounds through the introduction of element impurities such as boron and nitrogen. The impurities that boron and also nitrogen send blue and also yellow/brown color to the Diamond, respectively.



These impurities space scattered in the whole crystal yet do not get involved in the framework of the crystal. Now, over there is much more than one kind of element i.e., carbon, nitrogen, or boron, which make diamond a compound.

Let us discuss some properties of the Diamond, an allotrop of the carbon atom.

Properties of Diamond

As we currently stated that the diamond is a solid allotrope of the carbon atom. The carbon atoms are arranged in a cubic structure.

It is a natural material through the highest possible hardness and also thermal conductivity. Hence, diamond is provided for cutting and also polishing. For example, A diamond cutter is used for cut glass.

The electrical neutrality and also hardness the the Diamond can be taken by its decision structure. Permit us recognize the structure of Diamond along with the explanation that its distinct properties.

Structure of Diamond

The framework of diamond in regards to bonding is similar to other many stable allotrope of carbon atom i.e., Graphite.

In the crystal structure of Diamond, the carbon atom is tetrahedral and covalently bonded to the other 4 carbon atoms. It outcomes in the formation of a covalent network lattice, i beg your pardon is extended in all 3 directions.

Hence, the crystal structure of Diamond would be:


We can observe the each carbon in the covalent network lattice is sp3 hybridized, which can be figured out from the steric variety of carbon atoms.

The steric variety of an atom is defined as a summation that the variety of bond pairs and the number of lone pairs on the atom.

Here, in the framework of the Diamond, the number of bond bag on carbon atom = 4, number of lone pair top top the carbon atom = 0,

Hence, the steric variety of the carbon atom is 4, which outcomes in sp³ hybridization.

The covalently bonded network lattice results into the cubic structure, which can be represented as:


Let us see how can we relate the framework of the Diamond v its distinctive properties.

Structure-Property partnership of Diamond

The unique properties that the Diamond have the right to be explained based on their covalent network lattice.

These distinct properties space the highest possible hardness, an extremely high melting point, electric neutrality of the Diamond, non-conductor the electricity however the finest thermal conductor, and also high optical dispersion.

Let us talk about the relation of the distinct properties the the Diamond through its framework i.e., the large Covalent network lattice.

Hardness: The covalent bond connected in the structure of Diamond is really strong. Hence, the huge covalent network that Diamond outcomes in its greatest hardness out of organic minerals ~ above earth.

Melting point: The melting point of the Diamond is very high i.e., 4027° Celsius owing to the solid covalent bond.

The exciting fact the the Diamond have the right to never it is in melted together it is converted to the thermally stable kind of the carbon atom, Graphite, in ~ high temperature rather of melting.

Electrical Neutrality: there is no fee on any carbon atom in the crystal structure of the Diamond and hence, the is electrically neutral.

Non-conductor of Electricity: The crystal framework of the Diamond likewise reveals the there is the absence of lone pair ~ above the carbon atom or we deserve to say over there is no delocalized electron because that conduction the electricity.

As all electrons space localized in the bond, Hence, Diamond does not conduct electricity. However, the other kind of the carbon atom i.e., Graphite conducts electrical power owing to the existence of delocalized electrons

Optical Dispersion: Diamond can disperse irradiate of different colors and hence, it has high optical dispersion as contrasted to other forms of the carbon atom.

Thermal Conductivity: The diamond is the best thermal conductor in ~ room temperature due to the easy of the ingredient atom i.e., the carbon atom, and solid covalent bonding in between carbon atoms.

The room temperature thermal conductivity the the Diamond is 2000 W/m.K. That is 5 times greater than copper metal, i beg your pardon is a great thermal conductor.

Now, i think you are persuaded that the distinctive properties that Diamond are concerned its structure, i m sorry is various from another type of the carbon atom, i.e., Graphite.


In conclusion, we have studied even if it is the Diamond is an facet or a compound.

We conclude that Diamond is an element owing come the visibility of only one form of element i.e., the carbon element.
