Diamond is pure, crystalline Carbon.
It is one of the hardest natural substances known, and attributes it's hardness to an isometric octahedra crystalline structure which is very rigid and tough.
Diamond atoms are more densely packed together than are the atoms of any other natural substance.
The interior of a diamond is the same as the exterior: a matrix of carbon atoms. If a gem-quality diamond, these atoms lack some level of inclusion of any other mineral. If industrial diamond, the level of inclusions of other minerals render the diamond opaque or cloudy.
Diamond atoms cannot be split using normal chemical reactions because they are held together by strong covalent bonds. To split diamond atoms, extremely high temperatures and pressures would be needed to overcome the bond strength.
Scientifically, "...the atoms of the diamond mineral are packed more closely together than are the atoms of any other substance." Read more, below.
Millions/billions. However, they are all CARBON atoms. This is because diamond is an ALLOTROPE of Carbon. Any one carbon atom will be combined in a single bonds to four adjacent carbon atoms. Allotropes are when a given element displays itself in a certain manner. Other allotropes of carbon are Graphite , and Buckminster Fullerene (Footballene).
Diamond is the highest density, natural material; diamond atoms are packed more closely together than are the atoms of any other substance. As to why, when diamonds are formed in the earth's mantle under extreme pressure and extreme heat, this density is the result.
Everything is made of atoms.
There is no such thing as a "diamond molecule"; a diamond is just crystalized carbon atoms. In another sense, a diamond is one big, visible molecule. A one-carat diamond is one big molecule weighing 0.2g and having 10 sextillion atoms. Lots and lots of atoms!
No, diamond is not a silicate. Diamond is composed of carbon atoms arranged in a crystal lattice structure, whereas silicates contain silicon and oxygen atoms in their chemical composition.
This is because the carbon atoms are arranged differently in diamond and graphite. In a diamond, the carbon atoms are in a three dimensional crystal lattice structure. In graphite, the carbon atoms are arranged in a two dimensional sheet.
There are 8 diamond cubic atoms present in a single unit cell.
yes, diamond is made of carbon. Diamond is a macromolecule made of many carbon atoms. Each carbon atom is joined to 4 more carbon atoms each. Having each atom of carbon bonded to four other atoms is why diamond is so hard- there are lots of strong chemical bonds to overcome.
