Coal is an impure carbon, it has impurities like oxygen, nitrogen, sulphur etc. Diamond requires a very pure form of carbon. Diamonds are formed much lower on Earth than the levels at which coal is formed. …
What are the similarities and differences between coal and diamond?
What is the difference between coal and a diamond?
|3. Diamond require much high pressure and heat to be Manufactured||3.Coal does not need much pressure and heat.|
|4. Diamond is pure in nature||4.Coal contains impurities of other Elements as well like Oxygen, Sulphur, Nitrogen etc.|
What is the difference between coal graphite and diamond?
Coal actually isn’t a mineral (and isn’t pure carbon), but graphite is. … Thus any kind of pressure will cause the sheets to fry apart, which is why graphite, unlike diamond, is so soft. Answer 5: The reason diamond is so hard has to do mainly with its crystal structure, which describes how the atoms pack.
What is the similarity between coal and diamond?
Explanation: Diamonds and coal are both, at their base, different forms of the element carbon (C on the periodic table). And yes, pressure is a key part of what turns decaying carbon-based life forms such as plants into coal, as well as what turns carbon into diamonds.
What are some differences between carbon and diamonds?
What is the Difference Between Carbon and Diamond? Carbon is a chemical element having atomic number 6 and chemical symbol C while diamond is the strongest allotrope of carbon. The key difference between carbon and diamond is that carbon is a chemical element whereas diamond is an allotrope of carbon.
Is coal more useful than diamond?
A one pound diamond is worth anywhere from $2-6M depending on its grade. A pound of coal is worth a few pennies. Paradoxically, though diamonds cost more than coal, coal is more valuable.
Why diamond and coal are basically different forms of carbon?
On its own, carbon cannot form diamonds under the surface of the Earth. … Both coal and diamond are made primarily from carbon, but their chemical structures are significantly different. Coal is formed from highly impure carbon that often contains elements like oxygen, selenium, hydrogen, nitrogen and sulfur.
What are 5 differences between diamond and graphite?
Difference between diamond and graphite.
The p-Block Elements.
|4. It has huge three dimensional network structure.||4. It has two dimensional sheet like structure.|
|5. It does not possess any lustre||5. It a has metallic lustre.|
|6. It a has very high melting point.||6. It has low metling point.|
What are 3 differences between diamond and graphite?
For example, Graphite and diamond are two different allotropes of carbon.
Explain the difference in properties of diamond and graphite on the basis of their structures.
|1) It has a crystalline structure.||1) It has a layered structure.|
|2) It is made up of tetrahedral units.||2) It has a planar geometry.|
What is difference between coal and graphite?
is that coal is (uncountable) a black rock formed from prehistoric plant remains, composed largely of carbon and burned as a fuel while graphite is an allotrope of carbon consisting of planes of carbon atoms arranged in hexagonal arrays with the planes stacked loosely that is used as a dry lubricant and in “lead” …
What element are both coal and diamond are made of?
Diamond (left) and graphite (right) are both made of carbon, but their atomic structure is what makes them look so different from one another. Click to enlarge. Surprisingly, these gems are made of only one element, carbon. Carbon is the same element that makes coal or graphite used for pencils.
How Are diamonds made?
Diamonds are made of carbon so they form as carbon atoms under a high temperature and pressure; they bond together to start growing crystals. … As other carbon atoms move into the vicinity they will attach on. That’s the way any crystal grows.
Which is more valuable gold or diamond Why do you say so?
Since the value of gold is predictable and stable, gold has more value than diamonds. Natural diamonds are created when carbon is subjected to extreme pressure over millions of years. … Only a highly prized diamond, like a very large stone or an unusual color, will hold its value or become more valuable over time.
What is the main difference between diamond and graphite?
Although there are many differences between these two substances, the main difference between diamond and graphite is that diamond is made out of sp3 hybridized carbon atoms whereas graphite is made out of sp2 hybridized carbon atoms.
What are the differences in properties between diamond and graphite?
Graphite is opaque and metallic- to earthy-looking, while diamonds are transparent and brilliant. Another important physical difference is their hardness. The hardness of minerals is compared using the Mohs Hardness Scale, a relative scale numbered 1 (softest) to 10 (hardest).
Why is diamond and graphite different?
Both have Giant Covalent Structures, resulting in very high melting temperatures. However each carbon atom in Diamond has 4 covalent bonds with other Carbons, making it extremely strong and hard. On the other hand, each carbon in graphite is bonded to three carbons, and therefore graphite is formed in layers.
