Diamond is the hardest material known to man. Diamond is a form of carbon which has been compacted and gained a crystalline form due to intense pressure in the earth's crust. Therefore, carbon can be the hardest element.
carbon or tungsten
Yes it is. They are essentially compressed carbon; when the carbon is at a very high temperature and under very high pressure, the bonds are formed. Natural diamonds are made 180km below the earth’s surface. The temperatures at this depth are between 1100o c and 1400o c. Diamonds rank 10 (the highest) on the Mohs scale, range from transparent to opaque and is not affected by any chemicals.
More information is needed to properly answer this question. The top 10 hardest firms in the world is too broad. Do you mean the hardest firms to get hired by, the hardest firms to work for, the hardest firms to sue?
diamond is the hardest thing on earth
the softest rock is talc and the hardest is a diamond
Silicon Dioxide (known as Quartz) is not the hardest mineral, the hardest mineral is an allotrope of carbon called diamond. Quartz is only the 7th hardest mineral.
diamond
the hardest element is osmium, number 76 on the periodic table.
Diamonds.
diamond
Yes.
The hardest element is chromium, which is in group 6.

Earth would have to be the hardest of the Aristotelean Elements as it is the only solid one.
Carbon because of Diamond!
iron
neither its tungsten, a diamond is harder but it is not an element since it is not in the periodic table.
