**Potassium is the eighth most abundant element on Earth; accounts for 3% of Earths mass

**Incredibly reactive, almost never free in nature

** Element name from English Potash, Atomic symbol from the Latin word for alkali, Kalium1

Role in the human body:Electrolyte Helps prevent crampingAssists metabolism and ensures proper functioning of cells, tissues and organsEnsures electrical activity of heartNecessary for growth and building muscleHelps maintain acid-base balanceAssists in protein synthesisDeficiency or excess in system can cause serious problemsPotassium. . .Ways to Obtain Potassium:In Nature:Caustic potash, sylvite, carnallite, langbeinite, polyhalite By Humans:Red meat, fish, veggie burgersSoy productsMilk, yogurt, nutsVegetables: broccoli, lima beans, squash, etc.Fruits: bananas, kiwi, apricots, citrus, etc.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 pyrotechnicshttp://education.jlab.org/itselemental/ele019.htmlhttp://www.nlm.nih.gov/medlineplus/ency/article/002413.htm Lianne Makatura2

Calciumatomic number 20Number of electrons= 20Number of protons = 20Number of neutrons = 20Atomic mass = 40Symbol = Ca

Atomic StructureISOTOPES:Ca 42Ca 44Ca 46Ca 48* Part of cement* Part of quicklime (used to make paper, pottery, food, and purify water)

Where is calcium now?Who knew!In our foodCalcium is in milk and dairy products as well as leafy green vegetables. In our BodiesCalcium is obtained in our bodies to help strengthen teeth and bones. It helps stop bleeding and lower cholesterol.

Magnesium!Created by: Kylie Gruppo

Atomic Number: 12Protons: 12Neutrons: 12Electrons: 12Atomic Weight: 24.305The Facts:Isotopes:24Mg 79%25Mg 26MgRole in the Human Body:Vital component of a healthy dietLow levels related to the development of many illnessesAsthma, Diabetes, OsteoporosisHelps to strengthen bones & in muscle/nerve functioning

Obtained by humans through foodGood sources of Mg: spices, nuts, tea, & green vegetablesMacromoleculesFound in proteinIndustryUsed in foodsAutomotive industryInteresting FactsStable forms of magnesium are produced in starsIts made from the fusion of helium and neonMagnesiumhttp://en.wikipedia.org/wiki/Magnesium#Biological_roleOxygen 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.

AtomicNumberAtomicWeightSymbolOxygen 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.

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.
