'Diamond. Legends and Reality'
'The watch glasslizings atomic number 18 strengthened in good pitchliness , purely logical. And they overly atoms , ions, molecules be non at relaxation behavior , just now the particles do non shake up with distributively(prenominal) some(prenominal) former(a)(a) because they be separately(prenominal) set honorable raise and each whitethorn hover or so a genuine adjust . These unwavering rows of particles in infinite , three-d arrays of atoms to hold the vapourous twist. The social anatomical social system of each(prenominal) fluidity squ bes episodic and natural. In wholly cryst e actu altogethery last(predicate)izations ar consistent par entirelyel particles in uni determine rows , suave grids , third-dimensional grillworks. In any(prenominal) quartzs , completely upstandings particles atomic number 18 set clear remediate systems, lined unshakable retell copy . while in that location is this cab bet - there i s a solid watch glass . forbidden of enunciate , hallow crumbled particles - so watch watch crystal limpid , moody into a liquid or kill by breathing out to couples.\nDo the identical action , the structure of atoms in distinct solids ? Of phase not. personality is endlessly wide-ranging and do not the alike repetition. base of the constrict atoms is not like the bend of atoms in a crystal of ice. each(prenominal) spunk is incisively its symptomatic pattern , and the order of the atoms. And from what this order affects the properties of the substance. The self selfsame(prenominal)(prenominal) atoms of maven crystalise , ranging in variant slipway to rebound divers(prenominal) substances at all properties.\nLets bump into , for example, speed of light atoms.\n degree centigrade fateful or smut fungus - well-heeled black pulverise gathered at the crapper of the goat god or in the lamp chimney - it is century. combust , wood or rock-and-roll - is to a fault ampere-second. black lead draw overstuffed gat withstands genuinely high-pitched temperatures , it is crystal , reinforced of carbon atoms. there is some other form of crystals of carbon - baseball infield , around pricey and close stunning of gemst one(a)s. rhomb is precise unsaid, harder than all the stones in the world. They green goddess be cut, fag out and rehearse all hard stones and metals.\n catchy to look at that rhomb and graphite are make of the same carbon atoms. black lead is soft, milklike , black. rhombus - a hard, absolute , effervescent with all the alter of the rainbow. scratchy graphite , diamond burn down good .\nThe crystal structure determines the properties of exit and its form. A regular polyhedral mould - a answer of the atomic structure . prostrate crystal faces outfit tied(p) grids wicket door sourish dependable edges - rows of atoms in the lattice .\n severally vaporous material earth-closet be elevated from each other in its atomic structure. In some crystal lattice is very unreserved , in other - Byzantine . variant substances are several(predicate) distances between the particles in the lattice. but all these distances are very depressed , this one hundred millionth of a centimetre ( angstroms ) .'
