PERIODIC TABLE OF ELEMENTS

• IS A DIAMOND AN ELEMENT?

The periodic table of elements is only for, well, elements. A diamond is not an element, it is a mineral. An element is a compound or molecule that cannot be broken down into anything smaller, example: hydrogen, oxygen, even gold. Diamond isn't an element therefore it cannot be in the periodic table. It is a compound composed completely of Carbon, an element with atomic number 12. Graphite is also completely composed of Carbon yet is very different to diamond in its physical and chemical properties. i.e diamond is glassy, colourless and hard, graphite is dark grey/black and is soft. This has to do with the arrangement of the carbon atoms in each compound respectively.

WHAT´S A DIAMOND ?

• In mineralogy, diamond (/daɪᵊmənd/; from the ancient Greek ἀδάμας – adámas "unbreakable") is a metastable allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice. 
• Diamond is less stable than graphite, but the conversion rate from diamond to graphite is negligible at standard conditions. 
• Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. 
• In particular, diamond has the highest hardness and thermal conductivity of any bulk material. 

• Those properties determine the major industrial application of diamond in cutting and polishing tools and the scientific applications in diamond knives and diamond anvil cells.

Pressure resistance

Used in so-called diamond anvil experiments to create high-pressure environments, diamonds are able to withstand crushing pressures in excess of 600 gigapascals (6 million atmospheres).

Electrical conductivity

Other specialized applications also exist or are being developed, including use as semiconductors: some blue diamonds are natural semiconductors, in contrast to most diamonds, which are excellent electrical insulators. The conductivity and blue color originate from boron impurity. Boron substitutes for carbon atoms in the diamond lattice, donating a hole into the valence band.

Substantial conductivity is commonly observed in nominally undoped diamond grown by chemical vapor deposition. This conductivity is associated with hydrogen-related species adsorbed at the surface, and it can be removed by annealing or other surface treatments

THE MINERAL DIAMOND

Diamond has many unequaled qualities and is very unique among minerals. It is the hardest known substance, it is the greatest conductor of heat, it has the highest melting point of any substance (7362° F or 4090° C), and it has the highest refractive index of any natural mineral. Diamond is number 10 on the Mohs scale, and is 40 times harder than Corundum, which is number 9 on the Moh's scale. It also has the most dense atomical configuration of any mineral, and is transparent over the greatest number of wavelengths. Because of heat conduction, Diamonds are cold to the feel at or below room temperature. When heated, a Diamond will remain hot long after the heat source is removed.
