| COOL STUFF PLEASE SIGN MY GUESTBOOK -ANY FEEDBACK (GOOD OR BAD ) IS APPRECIATED If you're interested in magic ,then goto this fine site ,where you can learn advanced and impressive magic tricks for free : http://www.magic-net.co.uk 1.The rarest element on the Earth’s crust is astatine with 0.0056 ounces . 2. The commonest element is Iron ,which contributes to 36% of the Earth’s mass . 3.The element with the biggest molecule is element #112 (atomic # : 2770 4.Densest metalat room temperature is osmium is 0.8161 lb3 5. Lightest metal at room temperature is Lithium at 0.01927 lb3. 6. Tungsten has the highest melting and boiling points , with the melting point being at 6177 deg.f ,and the boiling point at 10550 deg.f ) 7.The metal with the lowest melting point is mercury with its melting point at -37.892 deg.f ,and its boiling point at 673.92 deg.f . 8.The hardest element is the diamond allotrope of carbon (whatever that is !!!!!!!!!) 9.The element with the highest expansion rate is cesium at 94 * 10-5 per degree C. 10 .The element with the lowest expansion is diamond at 1.0*10-6 per degree C. 11. The most durable element is Gold ,when 1 ounce can be drawn 43 miles . 12.The strongest pure metal is Iridium ,with a tensile strength of 550 Mpa (8.0 * 104 lb per inch ) . 13. The most toxic element (the severest restriction on acceptable level limits (954 times more restricted than the acceptable dose of radiation ) is radiothorium’s limit 2.4*10-16 g/m3 . 14. Tin has the most isotopes with 38 . 15 .Hydrogen has the least isotopes with 3 . 16.Tellurium is the most stable radioactive element ,with a half life of 1.5*1024 years . 17.Lithium is the least stable radioactive element ,with it’s 5-Li isotope’s half life of 4.4*10-22 seconds . 18.The strongest acid is an 80% solution antimony pentaflouric in hydrofluoric acid (it is so strong ,that only a 50% solution could be measured ,but even this was 1018 times stronger than concentrated sulphuric acid !!!!!!!!!!!!!!!!!!!!!) 19 .The most lethal man-made substance is TCDD (2378-Tetrachlorodibenzo-p-dioxin ,which is 150000 times more deadly than cyanide !!!!!!!!!!! ,and is a class A carcinogen (If 1000000 molecules hit your body ,you are guaranteed to get cancer ,and 1 billion molecules hit your skin you will automatically die ) 20. The highest temperature created by man was 918 ,000,000 deg.far –30 times hotter than the sun !!!!!!!!!!!! 21. The hottest flame created by man was when carbon subnitride was burnt at 1 atmosphere ,producing a flame that was a cool (!?!?!?!?!?!?!?!?!?!) 9010 deg.far . 22.The lowest temperature ever produced was when helium was cooled in a nuclear de-magnetization device in Helsinki ,reaching 280 trillionths of a degree . 23 .The fastest man-made velocity was made when a plastic disk was fired at 334,800 m/ph . 24.The highest man-made current was 2 million amps/cm2 . 25 .The highest voltage made was 32 million volts !!!!!!!!!!! 26 .The brightest light ever made was 10-20 watts per cm2 (whatever hat means !!!!!!!) ,and the pressure in the argon laser which achieved this had a plasma pressure of over 1 billion atmospheres !!! 27.Water is scientifically the weirdest substance ,cos where most substances shrink when they are cooled ,water expands ,and unlike most substances ,water is less dense as a solid than as a liquid .It needs 10 times as much energy to heat as iron and dissolves almost anything !!!! 28 .Chocolate is scientifically proven to be the most complex chemical (excluding additives and preservatives ) !!!!! 29. The densest material which has been discovered ,or at least suspected ,is a neutron star ,where a pinhead amount weighs 1 million tonnes !!! 30 .The shortest lived element is Seaborgium ,which lasts not more than half a minute ,and only a few atoms have ever been produced !! 31. Believe it or not ,silk is the strongest natural substance . 32.Some of the producers of the most poisonous natural poisons known to man are microscopically small .The tiny sea weeds get into shell fish and kill people when they eat the shellfish . 33.The most reactive element is fluorine ,which will burn anything in its path ,and platinum is one of the only substances which isn’t dissolved by fluorine ,that’s why it can be expensive !!! 34.The most pungent smell is ethyl-mercaptan ,which is said by some people to smell like rotting cabbage ,garlic,onions,burnt toast and sewer gas all mixed into one !!! The smell is even believed to be responsible for people to faint with the smell !!! PHWOAR !!!!!!!! 35. The highest pressure ever produced was produced by a hydraulic press producing 1.7 million atmospheres . 36.The most powerful nerve gas is Ethyl s-2-diisopropylaminoethylmethylphosphonothiolate ,or VX ,in 1952 ,which is 300 times more powerful than the nerve gas used in world War II . 37 .The thinnest wires were made in 1995 ,when nickel wires were made to just three nanometers thick (3 billionths of a metre ) 38. The sharpest thing ever made was a glass pipette ,being 0.01m thick ,which is 6500 times thinner than a human hair . |
