Do you know that..

1. Tungsten has highest m.p (3300centigrate). So it is used as a filament in bulb.

2. Most Electrons Prefer Bonding=MEPB= Methane Ethane Propane Butane.

3. Rub the petals of a red chinarose on a piece of white paper and let it dry for two minutes in air. Now just put a single drop of lemon sap on it, you will see a color change from blue to red. Here you have made a litmus paper- a quick and simple way to test the presence of acid and base.

4. Oxygen is not the most abundant element in our atmosphere. The most abundant element is Nitrogen, 78% while Oxygen is 21% and Argon is just short of 1%. Carbon Dioxide and trace elements make up the rest.

5. Xenon hexaflouroplatinate (XePtF6) is the first compound with a noble gas in it. It was first produced by Neil Bartlett in 1962.

6. Berrylium-8 has the shortest half-life, 70 x 10^-18 seconds, or 0.000000000000000070 seconds.

7. The lowest temperature reached in the laboratory is 7 nanokelvins, very near to absolute zero. The temperature was reached when helium was cooled to become a superfluid -- a fluid that could defy gravity.

8. Cops got the nickname because buttons on their uniforms use to be made of copper metal. In England, policemen were nicknamed "coppers" and the US has shortened this to "cops."

9. Rubber like you see on wheels of vehicles is actually one giant molecule.

10. A diamond does not melt in acid. The only thing that can melt is the intense heat.

11. Red phosphorus is a non-metal. It is not malleable and forms acidic oxide, e.g.,

12. Graphite can be transformed into diamond by applying a temperature of 3000°C and pressure of 100,000 atm.

13. Lightning is 3 times hotter than the sun.

14. Oxygen + Hydrogen= Hydrogen Oxide which is the same as water H20!

15. Sam Kean in his book "The Disappearing Spoon" wrote that Lewis and Clark carried mercury laxatives with them on their famous trek. Today, archaeologists test the soil for mercury contamination to help identify their campsites.

16. Under the right conditions, snow can form from hydrates instead of pure water. Hydrates are 3-dimensional crystalline structures that are stabilized by small molecules such as methane, ethane, propane, carbon dioxide, etc. Snowballs made from hydrates will actually burn due to the hydrocarbons trapped in their water crystals.

17. A diamond and pencil lead are made from the same element (carbon).

18. It is a type of alcohol (C20H29-OH) that contains an ionone ring and hydrocarbon chain.

19. Most elements are metals and most metals are silver-colored or gray. The only non-silver metals are gold and copper.

20. The word "plumbing" comes from the word "plumbum", which is the old name for lead and the origin of its symbol Pb. Modern plumbing uses pipes made from PVC or copper rather than lead, which is highly toxic. However, you may find copper pipes with lead solder. Hard water tends to form mineral deposits which can protect against lead leaching into the water.

21. Chemistry is the study of matter and energy and the interactions between them. It is a physical science that is closely related to physics, which often shares the same definition.

22. Chemistry traces its roots back to the ancient study of alchemy. Chemistry and alchemy are separate now, though alchemy still is practiced today.

23. All matter is made up of the chemical elements, which are distinguished from each other by the numbers of protons they possess.

24. The chemical elements are organized in order of increasing atomic number into the periodic table. The first element in the periodic table is hydrogen.

25. The IUPAC name for water, H2O, is dihydrogen monoxide.

26. Each element in the periodic table has a one or two letter symbol. The only letter...
