Diamonds are a crystallized form of carbon. While its atoms are no harder than any other carbon atoms, the arrangement of those atoms makes diamonds the hardest natural substance known to mankind.

Why is diamond harder than graphite?
Diamond is harder than graphite because diamond has a more complex structure. Diamond's structure is like many pentagons connected together, each pentagon sharing a side with another pentagon or each pentagon sharing a point with another pentagon. All the points are linked together in some way. Graphite's structure is very loose, with its bonds forming layers. There will be one sheet of elements bonded together, but then another sheet of bonds of elements will lay on top of that, and there will be very weak bonds holding those sheets together. Diamond's intricate structure of interwoven bonds makes it much harder and stronger than graphite, which has bonds in loose sheets.
What experiment would show that both diamond and graphite are allotropes of carbon?
the diamond (the hardest mineral known to man) is made up of a tetrohydral shaped atom structure which is formed into a complex lattice arrangement in the element. Graphite by contrast is one of the weakest minerals known to man, because its atoms are bonded by very weak bonds in fragile layers/sheets above and below one another, but each layer is not bonded to the rest.The carbon-carbon bonds in both minerals are actually quite strong, but it is the application of those bonds that make the difference.The carbon atoms are arranged differently in diamonds and graphite. They are both carbon, but their internal structure is different. They are allotropes of carbon.
Why is bronze harder than pure copper?
The atoms of pure copper are highly ordered and packed, which allows for a high level of malleability and ductility (meaning it bends easily.) However, if you add in some tin atoms, because tin is a much bigger atom than copper, it restricts the movement of those copper atoms, which overall makes the alloy harder and less "bend-y."
What properties do giant covalent structures have?
A giant covalent structure is an element made with very strong bonds between the atoms too create various materials. A couple of examples are Diamond and Buckminster Fullerine. Graphite is also one but has weak bonds aswell. like...
What does atoms mean in science?
Short answer: Atoms refer to those particles which constitute matter.

Why are diamonds so hard but carbon is not?
Although there are made from the same element (carbon), the chemical connections between diamonds atoms are several times more strong than those of carbon atoms.
Is diamond more dense than glass?
Diamonds are denser and harder than glass, as diamonds can score glass - as in a diamond glass-cutter.

Are diamonds used for roofs?
No, those shiny peices you see are not diamonds.
What happens to carbon to form a diamond?
The natural process that formed most diamonds requires that a "collection" of carbon is gradually placed under great pressure and substantial (but not too high) a heat, in the absence of oxygen, for many thousands of years. The site of their formation is within the upper mantle of the Earth, under the continental crust, and the resulting diamonds have ages between 1 and 3.3 billion years. There are also diamonds formed almost instantaneously by asteroid or meteor impacts, or manmade diamonds formed using very high compression. These "nanorod aggregate diamonds" are harder than normal diamonds, the manmade ones even more so. There are black diamonds called "carbonado" diamonds that may have formed within supernovas, or may have formed when the already concentrated carbon material impacted on Earth.
What would happen if you melted diamonds?
If you heated diamond in air it would turn to graphite - a more stable form of carbon - long before it melted. However, it can be melted if subject to 10 million times normal atmospheric pressure. When the pressure is reduced the diamonds will crystallised again. This has led scientists to speculate that there might be "seas" of molten diamonds on Neptune and Uranus because their atmospheres generate intense pressures and also are carbon-rich.

Who are the highest producers of diamonds?
The basic diamond producer is Mother Earth, who produces 100% of all natural diamonds. Other categories for diamond producer could include those who manufacture diamonds, those who mine them, those who broker them, those who cut them, and those who sell them. There is a highest producer in each of these specific categories.
How much is 19 diamonds?
Diamonds are valued by cut, colour, clarity and colour. Without those details, pricing 19 diamonds is not possible.
Who buys the pink Argyle diamonds?
People interested in owning fancy diamonds are likely to purchase pink diamonds, even those from the Agile mines.
Why do you think people buy blood diamonds when they know slavery is involved?
because those diamonds might be cheaper than other diamonds available
