Since they are both made of carbon their chemical properties are the same. Most physical properties of a solid like hardness, melting point, conductivity of heat/electricity, etc. largely depend on it’s crystal structure. Graphite and diamond have very different structures.
Do diamonds and graphite have the same properties?
The chemical composition of the two is exactly the same. This makes graphite and diamonds allotropes of carbon along with amorphous, which is commonly called soot or carbon black. Allotropes are compounds that have the same chemical makeup but have different structures which results in different properties.
What is similar between graphite and diamond?
Hint: An allotrope is another form of the same element having different physical properties but the same chemical properties. For example, Graphite and diamond are two different allotropes of carbon. They are different in physical properties but resemble carbon in chemical properties.
What are the common features of graphite and diamond?
Both graphite and diamond are composed of carbon atoms. Hence they both have an atomic weight of 12. They differ on other physical properties such as density, crystal structure, electrical conductivity, melting and boiling points etc.
Why are red diamonds worth so much money?
When it comes to colored diamonds, the biggest determining factor of their value is their rarity. Red is the rarest diamond color in the world. It’s so rare in fact, that it is thought that only 30 true gem quality red diamonds are known to exist.
Which is stronger diamond or graphite?
However, diamond is harder than graphite because of the carbon atoms in a diamond form 4 covalent bonds in the form of tetrahedral structure. While the carbon atoms in the graphite form 4 covalent bonds in the form of hexagonal structure. … This is the reason why diamond is harder than graphite.
What are the similarities and differences between graphite and diamond?
Diamond has a tetrahedral structure and is the hardest material known to man. There are strong covalent bonds between carbon atoms and each carbon atom is bonded to 4 other carbon atoms. Graphite has a hexagonal layered structure and each carbon is bonded via strong covalent bonds to 3 other carbon atoms.
Why does diamond not conduct electricity but is very strong?
Diamond is a giant covalent structure; each valence electron (outer shell electron) of every carbon atom forms a covalent bond, which means that there are no free electrons. Since electrical conductivity relies on the flow of free electrons, diamond is not a good conductor.
What is the difference between the structure of graphite and diamond?
Diamond: each carbon atom bonds to 4 other carbon atoms, WHILST, Graphite: each carbon atom bonds to 3 other carbon atoms. Thus, diamond bears more of a tetrahedral structure, whereas graphite takes the form of layers. The presence of layers means that atoms can slide over each other easily.
Why is diamond more expensive than graphite?
Also, as a result of the rarity, a Diamond is far more expensive than Graphite. Although they are made from the exact same component (Carbon), a Diamond differs from Graphite in the atomic structure. … In Diamond, all of the electrons are matched an covalent bonds to other carbon atoms.
Can a diamond conduct electricity?
Diamond is a form of carbon in which each carbon atom is joined to four other carbon atoms, forming a giant covalent structure. … It does not conduct electricity as there are no delocalised electrons in the structure.
Why is diamond so hard?
The outermost shell of each carbon atom has four electrons. In diamond, these electrons are shared with four other carbon atoms to form very strong chemical bonds resulting in an extremely rigid tetrahedral crystal. It is this simple, tightly-bonded arrangement that makes diamond one of the hardest substances on Earth.
What is the rarest gem?
Musgravite was discovered in 1967 and is arguably the rarest gemstone in the world. It was first discovered in Musgrave Ranges, Australia, and later found in Madagascar and Greenland. The first sizable gem-quality specimen was discovered in 1993.
What is the rarest diamond?
Quick answer: The rarest diamond color is the red diamond. They are so rare that less than 30 true red diamonds are known to exist. They can cost $1 million per carat and most of the red diamonds in existence are less than ½ a carat in size.
What makes red diamonds so rare?
What makes a diamond red in colour? Unlike other fancy colour diamonds that derive their colour from impurities such a nitrogen and borono, red diamonds are made purely from carbon, just like colourless diamonds. The red colour of the diamond is created by a rare occurrence in its atomic structure.
