POTASSIUM. . .Atomic Symbol: K Number: 19 Weight: 39.0983
Number of Protons: 19 Electrons: 19 Neutrons: 20
Isotopes: 22, with weights from 32-54Natural Isotopes: 39K (93.2581%) 40K (0.0117%) 41K (6.7302%)
**Potassium is the eighth most abundant element on Earth; accounts for 3% of Earth’s mass
**Incredibly reactive, almost never free in nature
** Element name from English Potash, Atomic symbol from the Latin word for alkali, Kalium
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
Potassium. . .
Ways to Obtain Potassium:o In Nature:
o Caustic potash, sylvite, carnallite, langbeinite, polyhalite
o By Humans:o Red meat, fish, veggie burgerso Soy productso Milk, yogurt, nutso Vegetables: broccoli, lima beans,
squash, etc.o 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

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.How iron is obtained by humans-Iron is consumed when humans eat meat, seafood, beans, greens, and vegetables.
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.
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.
Obtaining CarbonCarbon is obtained by mining coal from deposits, and then processing it for further use.
Role In Human BodyCarbon 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

Isotopes 25 known isotopes, 4 of which are stable The naturally occurring isotopes are found in hot springs, meteorites, volcanoes, and salt domes
How its Used in IndustrySulfuric acid is used to make fertilizers, adhesives, animal feed, cement, explosives, glass, fumigants, matches, and organic chemicals.
Role in the Human BodySulfur helps cells, seen as a nutrient.25% of body weight is sulfur
For the Human BodyUsed in lotions and creamsIngredient in many treatment medication for skin disorders
How its Obtained by HumansThrough food such as garlic and onionsElement itself is found in deposits buried underground
Type of MacromoleculeUsed in making proteins, two different amino acids contain sulfur:
Four Isotopes – N-13 with a half-life of 9.97 minutes– N-14 which is stable (natural)– N-15 which is stable (natural)– N-16 with a half-life of 7.13 seconds
Symbol: P Atomic Number: 15 Atomic Weight: 30.97376
Protons: 15 Neutrons: 16 Electrons: 15
There are no known naturally occurring isotopes.
Phosphorus-31 is the only type find in nature
Phosphorus Uses
Role in Human Body: Makes up large portion of cell membrane (phospholipids) Found in nucleic acids (macromolecule), energy compounds, and bones. Is necessary for muscle growth, to metabolize protein, calcium, and glucose (sugar),
bone and tooth formation, cell growth, and kidney function. 85% of phosphorus in the human body is found in the skeletal system.
Maintains the body’s pH level (acidity). We obtain it through dairy products, eggs, nuts, seeds, and meat.
Industrial Uses: Has a variety of uses: Used in match heads, military smokescreen, insecticides, rodenticides, fireworks,
