  2. Potassium. . . • Industrial Use: • Potassium-Sodium Alloy (NaK):heat transfer medium in nuclear reactors • Potassium Chloride (KCl): fertilizers, salt substitute, creation of other chemicals • Potassium Hydroxide (KOH): soaps, detergents, drain cleaners • Potassium Carbonate (KHCO3):glass and soaps • Potassium Superoxide (KO2): used in respiratory equipment • Potassium Nitrate (KNO3): fertilizers, match heads, and pyrotechnics • Role in the human body: • Electrolyte – Helps prevent cramping • Assists metabolism and ensures proper functioning of cells, tissues and organs • Ensures electrical activity of heart • Necessary for growth and building muscle • Helps maintain acid-base balance • Assists in protein synthesis • Deficiency or excess in system can cause serious problems • Ways to Obtain Potassium: • In Nature: • Caustic potash, sylvite, carnallite, langbeinite, polyhalite • By Humans: • Red meat, fish, veggie burgers • Soy products • Milk, yogurt, nuts • Vegetables: broccoli, lima beans, squash, etc. • Fruits: bananas, kiwi, apricots, • citrus, etc. http://education.jlab.org/itselemental/ele019.html http://www.nlm.nih.gov/medlineplus/ency/article/002413.htm Lianne Makatura

  3. Calcium atomic number – 20 Number of electrons= 20 Number of protons = 20 Number of neutrons = 20 Atomic mass = 40 Symbol = Ca Atomic Structure ISOTOPES: Ca 42 Ca 44 Ca 46 Ca 48 * Part of cement * Part of quicklime (used to make paper, pottery, food, and purify water)

  4. Where is calcium now? Who knew! Calcium is the 5th most abundant source in the earth’s crust Calcium has been known since the 1st century Lauren Mazzella http://chemistry.about.com/b/2010/04/30/calcium-facts-2.htm • In our food • Calcium is in milk and dairy products as well as leafy green vegetables. • In our Bodies • Calcium is obtained in our bodies to help strengthen teeth and bones. It helps stop bleeding and lower cholesterol. http://chemistry.about.com/od/elementfacts/a/calcium.htmhttp://education.jlab.org/itselental/ele020.html

  6. Iron has 4 energy levels • First energy level: 2 • Second energy level: 8 • Third energy level: 14 • Fourth energy level: 2 Color: silvery Classification: Transition Metal Crystal Structure: Cubic Element Symbol: Fe Atomic Number: 26 Number of –Protons: 26 -Neutrons: 30 -Electrons: 26

  7. How iron is used in industry -Iron is the cheapest and most abundant of all metals. -Iron is used to make paper clips to skyscrapers and everything in-between. -When added to other elements, Iron can give steel very useful properties. Isotopes existing in nature Mass #---natural Abundance---half life 56------------91.754%-----------stable 57-------------2.119%------------stable 58-------------0.282%-----------stable Role in the human body -Iron is the substance that caries oxygen within the red blood cells. - Iron is also used in the hemoglobin of the red blood cells that transports oxygen from the lungs to the rest of the body. Other interesting facts: -Iron’s chemical symbol comes from the Latin word for iron, ferrum. -Iron is the fourth most abundant element in the universe. How iron is obtained by humans -Iron is consumed when humans eat meat, seafood, beans, greens, and vegetables.

  8. Magnesium! Created by: Kylie Gruppo Atomic Number: 12 Protons: 12 Neutrons: 12 Electrons: 12 Atomic Weight: 24.305

  9. Magnesium The Facts: • Isotopes: • 24Mg – 79% • 25Mg • 26Mg • Role in the Human Body: • Vital component of a healthy diet • Low levels related to the development of many illnesses • Asthma, Diabetes, Osteoporosis • Helps to strengthen bones & in muscle/nerve functioning • Obtained by humans through food • Good sources of Mg: spices, nuts, tea, & green vegetables • Macromolecules • Found in protein • Industry • Used in foods • Automotive industry • Interesting Facts • Stable forms of magnesium are produced in stars • It’s made from the fusion of helium and neon http://en.wikipedia.org/wiki/Magnesium#Biological_role

  10. Atomic Number • Oxygen has 24 subatomic particles. • It has three stable isotopes. • It is found in fats, carbohydrates, proteins, and nucleic acids. • Oxygen, in gas form, is taken into the body by the action of breathing. It then enters the human's lungs. • Cellular respiration require oxygen to burn the calories from food. Also, oxygen is a component in many of the molecules in the human body. Symbol Atomic Weight

  11. Oxygen is used to treat sewage. • The steel industry uses oxygen to burn off impurities, such as carbon, sulfur, and phosphorus. • In industries, “oxyacetylene” torches burn the gas, ethyne, in oxygen. • In its excited states it is responsible for the bright red and yellow-green colors of the aurora. • Liquid and solid oxygen are pale blue.

  12. Atomic Number Atomic Mass Protons: 6 Neutrons: 6 Electrons: 6 Symbol Carbon • Isotopes: • 12C • 13C • 14C

  13. Carbon In Industry • rotating machinery & conducting electricity • pencils • jewelry • grinding machines • drill bits • glass cutting • fuels • bikes & motorcycles • Inks • paints • rubber products • cores of dry cell batteries • lubricants Role In Human Body Carbon is the building material of life and all molecules made of carbon are called organic. Without it, life would not exist. 18% of the human body is carbon. It is key in holding our bodies together as well as keeping minerals inside of us. Many minerals actually contain carbon. Since carbon has the ability to form many different bonds, it creates compounds that our bodies need. One compound would be carbohydrates which provide us with energy. Proteins, fats and nucleic acids are also forms of carbon found in living organisms. • Interesting Facts • Fourth most abundant element in the universe • One of the oldest elements • Made in the interiors of stars • Origin of the name 'carbon' comes from the Latin word carbo, for charcoal Obtaining Carbon Carbon is obtained by mining coal from deposits, and then processing it for further use.
