Atoms...As basic science will teach you, the strength of every material is based on how its atoms are aligned - in a gas they can freely float, in a liquid they are touching but can move and in a solid they are compacted together.

In Diamonds, the atoms are so closely packed together, so it is a very hard substance.

--------------------------------------------------------------

- Diamond has a specific crystalline structure: face-centered cubic as diamond lattice.

- Diamond has a very strong covalent bonding between carbon atoms.

Diamonds are composed of carbon atoms arranged in a crystalline structure, forming strong covalent bonds. This structure creates a rigid lattice that makes diamonds extremely hard. Additionally, diamonds have a high melting point and are resistant to both scratching and abrasion, contributing to their exceptional hardness.

The amount of pressure required to form a diamond is much greater than any other natural process involved in the making of any other compound. The molecules in a diamond are therefore closer together and the bonds between them much stronger than the bonds holding other substances together, thus they are harder.

the carbon atoms in a diamond are in crystal formation and are 'packed in' so closely and dense that the sub-atomic bond is incredibly strong. They just don't want to be pulled apart. that's why diamonds are so hard.

What rock is a red and yellow gemstone with a hardness of 7.5?

Only Diamond is as hard as diamond, and if their could be any gem stone as hard as diamond then it would definitely be Diamond.


A pure form of carbon that forms a very hard crystal?

Diamond is a pure form of carbon that forms very hard crystals due to its strong covalent bonds. Its structure is made up of carbon atoms arranged in a crystal lattice, providing exceptional hardness and high thermal conductivity.


Is a hard material easily scratched?

A hard material is not easily scratched, as its strong structure makes it resistant to scratches. Examples of hard materials include diamond and sapphire, which are known for their durability and scratch resistance.


Why diamond is so hard?

the diamond is very hard because it has crystallized at depth of 140-150 km( sometime it has crystallized at 300-400 km) into the earth to high pressure ranging approcimately betwen 45-60 kilobars and low temperature ranging approximately betwen 1652-2372 F(900-1300 C).AnswerIts hard because it consists of very small atoms (carbon) that are then tightly packed together and linked via covalent bonds (bonds where two atoms share an electron). It is the combination of very tight packing and very tight linking that results in diamond being so hard.


How to make graphite hard?

To make graphite hard, it needs to be transformed into diamond through a process called diamond synthesis. This typically involves subjecting graphite to high pressures and temperatures in a controlled environment to rearrange its atomic structure into the tightly packed, rigid lattice of diamond.
