-Sodlium, 11 th element, 11 electrons, -sodium element in water= fire in water(elemental hydrogen produced) -Ionic bonding (connections between elements) -Potassium and bromane  powerful reaction 2KBr, potassium bromide (K+, BR-, crystalline solid, high melting point) -Chlorine and Sodium toxic elements combine to create edible salt Vid 3 -Conduction of electricity in water -lemon juice (citric acid, ionize sufficiently to conduct electricty) -vinegar ( acidic acid, weak conduction, not well ionized compared to citric acid) -salt ionizes very well (conducts electricity well) -soy sauce( very well ionization, because of the sodium) -v8 juice (not as dramatic as soy, but has salt) Vid 4 -Na has 1 electon in outer shell, Cl has 7 electrons in outer shell -(first layer, 2elec, then 8, then the rest) -sodlium loses an electron thus positive, and Cl gains electron thus negative -salts will conduct electricity -lemon juice contains potassium and other minerals that conduct electricity Vid 5 -Salt bed in west coast of South America -Chile, Bolivia, have salt beds -Christopher Pratt “Salt Shed Interior” Minerals 2 Vid 1 -Calcium (mineral in diet), phosphorus , both impotant for teeth and bone -minerals=micronutrients (~1gram/day) -6 grams of salt= 40% sodium=2.4g =daily intake -microgram= 1/1000 of miilligram -one small cube of salt is 60 microogram ug -too much salt can lead to high blood pressure or hypertension Normal blood pressure 120/80 high blood pressure is 140/90 -high blood pressure, don’t eat dilled pickles, and instead of salt use herbs Vid2 -Potassium, same charge K+ - no salt, take potassium chloride (for ppl with high blood pressure) -bananas, high on potassium (50% more potassium from potatoes than bananas)

-Potassium (K+) and Sodium(Na+) different sizes, how much water can accumulate around ion -potassium bigger than sodium (balance of electrolyte concentration important for body) -potassium pumps water out Vid3 -Iodine (I-) ionic iodine -I2, elemental iodine, solid with interesting property (doesn’t melt, but sublimes) -deficiency of ionic iodine causes goiter (needed by thyroid gland for fat metabolism) -Theodore Kocher (nobel prize for thyroid work) -naturally present in seasalt and seafood -potassium iodide added in small amounts to table salt -150mcg per day to not have goiter -kazakstan, lack of iodide ion causes goiter -not present in salt mines of country -potassium iodide added to salt in the factories to relieve of having goiter -5c USD per person per year to solve problems of goiter Vid 4 Iron (Fe 2+), 2-4g in the body, 10-20 mg/day -in blood, to transport oxygen - iron deficiency=anemia - hemochromatosis (genetic) -body absorbs abnormal amounts of iron -when cooking was only in iron pots -excess iron stored in heart, liver, pancreas, joints - Heme, iron in large molecule of heme (transports oxygen) -in medieval times, put iron nails in wine, acidic components of wine, cause iron to go into solution to help health (dubious) -iron in red meat, broccoli, and best absorbed with vitamin C - vit C assists in absorption from gastrointestinal tract -iron can be added to food (such as bread as supplementf)
