ELEMENTS PRESENTATION
- Oxygen the most abundant element on earth It makes up 21% of the earth’s atmosphere
makes up 78% of our atmosphere - Nitrogen a gaseous non metal makes up 78% of our atmosphere its compounds are important components of proteins, fertilizers, and many explosives
Fertilizers are very important for agriculture
Hydrogen lightest and most abundant element. The fuel of the universe Hydrogen lightest and most abundant element. The fuel of the universe. Found in numerous compounds.
THE SUN
Carbon components of all living matter and fossil fuels Carbon components of all living matter and fossil fuels. The black material on a charred candle wick.
Phosphorous widely distributed nonmetal Phosphorous widely distributed nonmetal. Never found in its free, element state. It is an essential component in all cells.

fertilizers
Lithium highly reactive metal Lithium highly reactive metal. Used in the manufacture of synthetic rubber and drugs. Used to treat certain types of mental illness.
Sodium highly reactive metal compounds include table salt, lye and baking soda
Lead Soft, dense metal used in bullets and car batteries concern over its biological effects
Car Battery
Tin a metallic element a corrosion-resistant coating on the inside of cans and for packaging of foods
- Antimony it’s symbol comes from a Latin name it is used with lead in car batteries
Cesium most chemically reactive metal used in some photoelectric cells and atomic clocks helps make stainless steel
Solar panels and Stainless steel sinks
Magnesium a silver-white metal Magnesium a silver-white metal. Used in the transportation industry because it is strong and has a low density. Used in photo flash and fireworks because it ignites very readily.
Barium a reactive, metallic element Barium a reactive, metallic element. Its compounds are used as a medical “cocktail” to outline the stomach and intestines for X-ray examination. It’s compounds give green colors to fireworks.
- Chlorine highly reactive used as bleach, as a disinfectant (water purification), and as a poison gas
Helium unreactive, gaseous element that is a product of the nuclear reaction (fusion) of hydrogen atoms. The second most abundant element in the universe. It is used in Blimps
Manganese a metallic element it is added to steel to increase its strength.
- Gold a yellow non reactive metal highly valued since ancient times
Argon odorless, colorless unreactive gas used in most incandescent light bulbs
Zinc metallic element serves as a negative pole in a flashlight battery melted with copper it becomes brass
Krypton unreactive gas. Element that could weaken Superman Krypton unreactive gas. Element that could weaken Superman. In radio active form it is a byproduct of most nuclear weapons.
Tungsten highest melting point of any pure element.
Chromium helps make stainless steel if combined with nickel makes nichrome wire which is used in toasters
Bismuth a relatively low melting point used in fire extinguishers and electrical fuses
Copper a reddish, lustrous, ductile, malleable metal, occurs in nature in both free and combined states it forms the body of the statue of liberty makes pennies
Nickel one of the three magnetic elements used in five cent pieces
Fluorine a highly reactive, gaseous non metal added to tooth pastes and to many urban water supplies helps to prevent tooth decay
Calcium a reactive metal makes up limestone, chalk, cement, bones and teeth in animals milk is a good source of this element
- Cadmium a metallic element used in control rods in nuclear plants and in NiCad rechargeable batteries
- Bromine a red highly reactive fuming liquid with a foul smell limited use as a disinfectant it’s compound is a component of leaded gasoline
Iodine a solid purple-black non metal serves as a skin disinfectant
Boron used in certain glasses (Pyrex) used in soaps and drill bits and control rods in nuclear power plants
Aluminum the most abundant metal in the earth’s crust used in cars, boats and airplanes has low density
Potassium highly reactive metal with low density Potassium highly reactive metal with low density. One of three elements in fertilizer.
Uranium a silver white radioactive metal used as fuel in nuclear power plants, and in some atomic war heads
Neon an unreactive gaseous element used in advertising signs
Mercury nicknamed quicksilver Mercury nicknamed quicksilver. only metal that is liquid at room temperature. Used in thermometers, because it expands to heat.
Sulfur used in the tips of matches and in gun powder Its presence to coal leads to acid rain if it is not removed before the coal is burned
Cobalt a hard magnetic metal used in the production of steel used in cancer treatment
Silver This is the best conductor for heat and electricity It was used in manufacturing coins but soon it became too expensive It is now used in eating utensils and decorative objects
- Silicon The second most abundant element on the earth’s crust it is the principle component of sand and quartz found in solar cells, computer chips, caulking materials, and abrasives
Beryllium reactive metal with high melting point Beryllium reactive metal with high melting point. Used in manufacturing rocket nose, because it is strong and has a low density
Platinum an expensive silver white metal used in jewelry used to speed up chemical reactions
