Element: H (Hydrogen) Discoverer: Henry Cavendish Color: colorless Obtained from: mining, oil, natural gas wells Uses: Was used in ancient lift air balloons as used to working day meteorological send balloons filled with hydrogen gas to explore the weather. Also, there is a modern trend now is to use hydrogen gas as an alternative fuel for petroleum products. Element: C (Carbon) Discoverer: Unknown Color: The probability that black Obtained from: burn with a little oxygen. Uses: Charcoal, another form of carbon, is used in artwork and for grilling (usually on a barbecue). _Activated charcoal (another form of carbon) is used as an absorbant or adsorbant in many filters. These include gas masks, water purifiers and kitchen extractor hoods. It can also be used in medicine to remove toxins, gases or poisons from the digestive system. _Diamond (yes, it’s another form of carbon) are used in Jewelry. Industrial diamonds are used to drill, cut or polish metals and stones. Element: O (Oxygen) Discoverer: Joseph Brista Color: colorless Obtained from: from liquid air. Uses: oxygen is important for human respiration. Therefore, oxygen therapy is used for people who have trouble breathing due to some medical condition (such as emphysema or pneumonia). _Oxygen gas is poisonous to bacteria that causes gangrene. Therefore, it is used to kill them. _Pure oxygen is used to ensure the complete combustion of different chemicals. _Oxygen is used to treat water . Element: N (Nitrogen) Discoverer: Daniel Rutherford Color: colorless Obtained from: Liquid Air Uses: Nitrogen is used to preserve packaged foods by stopping the oxidation of food which causes it to go ‘off’. _ Light bulbs may contain nitrogen as a cheaper alternative to argon. _Nitrogen gas is often used on top of liquid explosive to keep them from exploding! _ Used to manufacture stainless steel. _Nitrogen gas is used to fill the tires of aircraft and automobiles (cars). Element: Na (Sodium) Discoverer: Sir Humphry Davy. Color: Silver Obtained from: salt and other foods. Uses: _The main use of sodium is for making table salt, Sodium Chloride (NaCl). This is important to us because an average human uses 3 grams of salt in their body everyday and an average human usually takes in approximately 10 grams of salt everyday. _Sodium is also used in washing soda (sodium carbonate), soap, and baking soda (NaHCO3). These things are used in our everyday life. _Sodium can be used as a heat transfer agent and as a coolant for nuclear reactors. Sodium vapor is used in streetlamps to make a bright yellow light. _Sodium compounds are important to paper, glass, soap, textile, petroleum, chemical industries. Element: S (sulfur) Discoverer: Unknown Color: Yellow Obtained from: Nature Uses: Most sulfur is converted to sulfuric acid. Sulfuric acid is extremely important to many industries around the world. It is used in the manufacture of fertilizer, oil refining, processing wastewater, lead-acid batteries in cars. _ Sulfur can be used as a pesticide and fungicide. Many farmers that grow organic foods use sulfur as a natural pesticide and fungicide. _Sulfur is used to vulcanize rubber. Vulcanization makes rubber tougher. It ensures that rubber maintains its shape. Car tires, shoe soles, hoses and ice hockey pucks are all made from vulcanized rubber. IS there Really a Chemistry of Love There's attraction. Nonverbal communication plays a big part in initial attraction; the 'high' of being in love is due to a rush of phenylethylamine and dopamine. All is not lost once the honeymoon is over. Lasting love confers chemical benefits in the form of stabilized production of serotonin and oxytocin. Energy Everyday The carbohydrates gives us energy. vitamins used by our body tissues. Everyday Uses we use chemicals in the form of shampoo soap detergents in our daily life. Most of medicines are made by chemicals Paracetamol one and only chemistry With out chemistry we can not do any thing. for example morning brush, making tea or coffee, soaps , detergents, cosmetics chemistry in fuels chemistry done really well job in preparation of fuels such that there are many isomerism of alkane ,alkene and alkyne which is mostly used for preparation of fuel and also for preparation of diesel petrol and it also used for black ink Elements in the Human Body Most of the human body is made up of Oxygen (65%) Carbon (18%) Hydrogen (10%) Phosphorus (1.0%) Nitrogen (3%) Calcium (1.5%) Other important Elements and their sources 1.Calcium -Calcium is mandatory for building strong bones and teeth. It even aids in blood clotting and helps nerves carry messages, to keep our hearts beating properly. -It is recommended that adults between the ages 19-50 need 1000 milligrams of calcium per day, and adults aged 51+ need to increase their calcium to 1200 milligrams per day. -The best sources for calcium are: milk and dairy products such as cheese, cottage cheese, yogurt, rice, salmon, tuna, as well as broccoli, okra, and turnip greens. -Calcium deficiency can lead to a condition called osteoporosis, which causes bones to break easily. 2. Iron -Iron helps red blood cells carry oxygen to all parts of the body. Almost two-thirds of the iron in your body is found in hemoglobin. -The recommended daily allowance is for females 19-50 years: 18 mg and 51+ years: 8 mg -Excellent sources for iron are: red meat, pork, fish and shellfish, poultry, lentils, beans and soy foods, green leafy vegetables, and raisins. -A deficiency in iron may cause anemia which includes weakness and fatigue, lightheadedness, and shortness of breath. 3. Magnesium -Magnesium helps muscles and nerves function, steadies the heart rhythm, and keeps bones strong. It also helps the body create energy and make proteins. -The recommended daily allowance for females 31-50 years is 320 mg and 51-70 years 320 mg. -The best sources for magnesium are: whole grains and whole-grain breads, nuts and seeds (especially seasame seeds) green leafy vegetables, potatoes, beans, avocados, bananas, kiwi, broccoli, shrimp, and chocolate. -Magnesium deficiency include tremors, muscular weakness, confusion, nervousness, hallucinations and swallowing difficulties. 4. Zinc -Zinc is important for normal growth, strong immunity, and wound healing. -Zinc is necessary for protein synthesis and the metabolism of Vitamin A. - Zinc also helps the healing process of internal and external wounds, decreases cholesterol deposits and promotes mental awareness. -The recommended daily allowance for women is 12 milligrams per day. -The best sources for zinc are found in: red meat, poultry, oysters and other seafood, nuts, dried beans, soy foods, milk and other dairy products, whole grains, and fortified breakfast cereals. -A deficiency in zinc can cause loss of appetite, growth retardation and immunological abnormalities • http://chemistry.about.com/od/everydaychemistry/tp/Chemistry-In-Daily-Life.htm Reference: H.
