Why it is a element?

Pritam Paul said: (Dec 13, 2010)  
It is a mineral then why it called as a element. I think option B is right answer.

Amees said: (Jan 12, 2011)  
Diamond is the hardest mineral in the world.

Divesh Suvarna said: (Jan 16, 2011)  
Diamond is made of pure carbon, with carbon atoms arranged in a cubic structure and bonded to their neighbors in a very compact way.

So, diamond is made of an element but it is not an element. It is not a compound either, because, by definition, a compound is made up of two or more elements.

I would say diamond is crystalline form of carbon, that is, it is composed merely of carbon atoms in a highly structured arrangement.
It is carbon, like charcoal, but its more expensive due to its good properties and the fantastic marketing to the gullible public.

dimond is a form of carbon

Nagarajan said: (Apr 30, 2011)  

Suresh said: (May 16, 2011)  
Diamond is allotroph of carbon.


Bah said: (Jun 8, 2011)  
Probably Diamond is not the hardest substance on earth.

N. Shivprasad said: (Jul 17, 2011)  
Diamond has all the properties of carbon. Thats why it is an element.

Sad said: (Nov 3, 2011)  
Diamond is a hardest substance, diamond has a all properties of carbon.

Praveen said: (Nov 27, 2011)  
Diamond had a Mohs scale measurement of 10..
But there are some elements(not on earth i think so) which has greater that 10 strength, like carbon fullerenes e.t.c...

Firdous Ahmad Mala said: (Jan 2, 2012)  
Diamond is a form of Carbon. So, it is simply Carbon in disguise.

Naresh said: (Jan 11, 2012)  
How it is considered as a element ?

Amit Kanojia said: (Mar 22, 2012)  
Yes, by definition it is wrong that Diamond is an element but it is a form of carbon where one carbon atom bonded with other four carbon atoms and form tetrahedron shape. Due to this diamond is hardest substance.

Rakesh Ias said: (Apr 16, 2012)  
Diamond has all the properties of carbon thats why it is an element.

Kriti said: (Jul 5, 2012)  
Ruby, topaz, emerald and sapphire are the name of corals and pearls where as diamond is the allotropic form of carbon which is obviously a metal. Diamond is a example of covalent crystal. Covalent crystals are present only in metals. Hence diamond is also a metal.

Ruk Mangal said: (Sep 22, 2012)  
Diamond is made up of pure carbon so it is a element option (D) is correct.

Mohit Bhatt said: (Sep 25, 2012)  
Diamond's chemical formula is "C" and it gives CO2 on complete combustion. Hence it is a form of carbon (preferably allotrope of carbon).

Therefore we can conclude that diamond is an element.

Jagpal Mann said: (Oct 1, 2012)  
Diamond is allotrop of carbon not an element.

123 said: (Feb 7, 2013)  
Diamond is an allotrope of carbon but carbon is itself an element hence diamond must be an element.

Ruby, sapphire and emerald are gemstones or minerals but diamond is not a mineral.

Diamond is formed by cutting carbon at very very small angles to make it shine.

That's why its expensive.

Damilola said: (May 27, 2013)  
The correct answer is option D because diamond is an allotrope of carbon which means it has all the properties of carbon because carbon is an element itself.

Nayan Kumar Patel(Bsc Ag, Bca) said: (Jul 25, 2013)  
An element is a substance containing an atomic no mass and the atoms of same types and Diamond is a substance which largely carbon atoms so it is regarded as an element.

Nitin said: (Oct 17, 2013)  
Diamond is a substance not an element. Please tell me the right answer.

Sandeep2013 said: (Oct 21, 2013)  
Why this element does not explain properly?

Goutam said: (Nov 5, 2013)  
Diamonds are made by an element how can it again become an element?

Hafiz Qureshi said: (Nov 16, 2013)  
Option D because diamond is made from carbon which is an element, hence diamond is an element.

Shlok said: (Jan 30, 2014)  
If it is an element why is it not included in the periodic table and if it is included then what's its symbol or atomic number?

Tiana said: (Apr 26, 2014)  
Substances which are made up of same type of atoms or molecules formed from joining up of same type of atoms are called elements. According to this diamond can be taken as a element.

Arnav said: (May 20, 2014)  
How can dimond be considered as an element its an mineral?

Nitish said: (Jul 8, 2014)

Hasan said: (Aug 10, 2014)  
Confirm D because in this question no compound present that made only one element but ruby, Sapphire, emerald consist of different element. Only diamond made by one element, carbon, but out of this question diamond is not correct answer for element, its nearly answer in this question.

Adlin said: (Sep 17, 2014)  
Diamond is the hardest element ever known.

Libin said: (Oct 6, 2014)  
Because diamond is the purest form of carbon.

Shadab said: (Nov 3, 2014)  
What type of metallic property you seen in diamond also it is accept ion case because diamond is a good insulator?

Saithali said: (Dec 13, 2014)  
How Allotropes come as element?

Manisha said: (Dec 29, 2014)  
I think Ruby because it is an element and diamond is the allotrope of carbon.

Hog Rider said: (Jan 20, 2015)  
Diamond is a allotrope of Carbon. And Carbon itself is a Element. So Diamond is also Element.

Roshithavk said: (Feb 16, 2015)  
Other three are minerals where diamond is allotrope of metal carbon.

Guy said: (Mar 24, 2015)  
Carbon = Atom = Element.
Diamond = 100% carbon.
Diamond = Carbon.

Diamond is Technically an Element because it IS 100% of a single element. Saying Diamond is an element is like saying.

"A house is made of wood, wood is used for building. So that must mean houses are USED for building also".

No, houses (Diamond) are made from building materials (Carbon) Houses are just the accumulation and joining of building materials to form a structure.

Hanamant Hukkeri said: (May 29, 2015)  
Diamond is not a element it is mineral only.

Agbo Edith said: (Jul 25, 2015)  
Well, on my own opinion, Carbon is the right answer. Not that it is an element but it is the major component of Carbon which is an element.

Kesentseng N. Sebele said: (Sep 10, 2015)  
On my own opinion, diamond is the right answer even though it is a mineral.

James Bond said: (Sep 30, 2015)  
Diamond is a pure carbon.

Nitesh Kumar said: (Nov 7, 2015)  
But as we know that diamond is not available in periodic table please tell on which base we can say it element.

Ram said: (Nov 23, 2015)  
It is allotropic form of carbon and not element.

Aero said: (Dec 26, 2015)  
It is both a mineral & element.

Taj said: (Dec 31, 2015)  
Actually a diamond is an object not an element. The element is carbon and the carbon molecules combine under extreme conditions to form a diamond. This example is no different than an iceberg.

An iceberg is comprised of water molecules that combine under extreme conditions to form an ice pack which can then break into icebergs. But an iceberg is not water, an iceberg is comprised of water molecules. In this way a diamond is comprised of carbon. The element is carbon and the diamond is an object formed of that element.

Taj said: (Dec 31, 2015)  
Ruby, Emerald and Sapphire are gemstones.

Aashish said: (Jan 22, 2016)  
Why other ones are not an element?

Cleopas Mutengwa said: (Apr 8, 2016)  
Totally amazing. Thank you all.

Sanjiv said: (Apr 18, 2016)  
Diamond is an allotrope of carbon it is made by only one element that is carbon. So it is taken as an element.

Diamond is purest carbon.

Ajay said: (Jul 26, 2016)  
What is Element? Describe.

Albert said: (Oct 2, 2016)  
An element is a pure substance that cannot be broken down by any chemical means? Describe it.

Jasna said: (Oct 11, 2016)  
Diamond only has properties of carbon[element].

Thirupathi said: (Nov 13, 2016)  
None of them is the correct answer for this. A diamond is an allotrope of carbon.

Tushar said: (Nov 23, 2016)  
Diamond is pure elemental carbon, compressed to its crystal form, under extreme heat and pressure deep within the Earth.

Lg Fighter said: (Dec 6, 2016)  
It is an element . Because the definition of an element is a substance consisting of only one type of pure matter, which in the case of diamond is carbon. The definition of a compound is a substance which consists of more than one "type" of the element, or two different elements. Even though it has carbon bonds, it consists of only one element (carbon), again it's is an element!

Anu said: (Dec 13, 2016)  
Diamond is the correct answer. I agree.

Yusuf said: (Mar 22, 2017)  
Diamond is an allotrope of carbon not an element.

Sapna said: (May 29, 2017)  
Diamond is the hardest mineral

Arun said: (May 30, 2017)  
Diamond is not an element.

Avinash S said: (Jun 15, 2017)  
I Confused. Diamond Is Purely Made From Carbon. But It is Not An Itself Element. Right?

Tarannum said: (Jul 22, 2017)  
Comparatively, it is an element but actually, it is a compound. So in this question, there is one option we can go for is Diamond otherwise if any option would have been "NONE OF THE ABOVE" then we would have to go for that.

Satvik said: (Jul 27, 2017)  
I would think the diamond is correct answer cause it is a form of carbon rather than ruby sapphire are natural occurring gem stones.

Nazim said: (Aug 2, 2017)  
Diamond is not an element.

Pooja said: (Aug 17, 2017)  
Diamond is an allotrope of carbon how it becomes element?

Dave said: (Aug 25, 2017)  
Diamond is made up of elements, but it is neither an element nor metals. From the question, the other substances are forms of gemstone, so diamond will be the answer. But there must be a reasonable prove to the fact that diamond is an element.

Manoj said: (Oct 29, 2017)  
Because it is an allotrope of carbon while others or mixture of some Elements.

Aritri said: (Jan 9, 2018)  
It's an element because it contains the same kind of atoms and molecules.

Dhendup said: (Jan 31, 2018)  
Diamond is an allotrope of carbon(C), right!

But if you think logically, then Diamond is also a carbon(C).

Now when carbon(C) is an Element, why not the diamond(C) be an element?

Both carbon and diamond are exclusively made up of carbon atoms and no other.
Hence, carbon is an element because it only contains carbon atom, so diamond is correct.

Aakash said: (Mar 8, 2018)  
Thanks for explaining the answer.

Shadan said: (Mar 16, 2018)  
Diamond found in pure form so it is an element.

Gaurav said: (May 30, 2018)  
Diamond is an allotrope of carbon.

Here all others are minerals.

And diamond is made up of carbon only.

Meanwhile, it is not an element but it's a homogeneous compound of carbon which is closest to the element. Hence, it is referred here as an element.

Hira Lal said: (Sep 28, 2018)  
Diamond is allotrope of carbon it is not an element.

Cloyd said: (Oct 19, 2018)  
Diamond is the pure carbon.

Swar said: (Feb 19, 2019)  
Diamond is a pure element of carbon.

Shankar Rajak said: (Apr 12, 2019)  
Option B is the right answer.

Rahul Nakod said: (May 26, 2019)  
Ultimately diamond is a carbon and carbon is an element.
