What makes the diamond the hardest mineral?


I have heard that something other is harder than a diamond, but I am not sure. So I don't really care about the other things, because I don't know them. So what makes the diamond, not other minerals, the hardest mineral?|||It's hardest because of it's chemical make-up. It's made of carbon and carbon atoms fit very well to each other. There is no space between so the object becomes very stable. Also, for diamonds, millions of years under the ground being squeezed by all the weight of the rock around it changes it from just being coal or some other form of carbon to diamond.|||Diamond has coherent binding by cubic structure of carbon atoms.|||diamond is made of cardon atoms...these atoms are held by strong covalent bonds....each cardon atom is attached to 4 other cardon atoms.....|||Diamond is carbon which has been formed as crystals under extreme compression and heat in a volcano. It's hardness comes from the structure the atoms form under these conditions.|||it is covalently bonded and it has acrystal lattice and the other hardest is graphite.|||it's crystaline structure. every mineral has a unique crystaline structure. This determines the type of mineral it is and how hard it is.|||Each atom in a diamond melecule is joined to 4 or 5 other atoms. This makes it compressed and hard.|||the 2 to 3 dimensional lattices of carbon makes it the hardest material,it's all due to carbon atom.


the have three basic properties:


1.they form covalent bonds with large no of other elements


2.they can extend themselves to form such covalent bond with 4 different types of atoms


3.the form covalent bonds by sharing electrons in different ways,this bonds r very hard





so carbon is behind all this when they form short chains they result into gas and when long chains they form solid,i don't know more than this as I'm a student studying in 10Th standard of Gujarat state in India
