The Periodic Table

Power point 2010By: Corey Weidner

Gold

Gold has been widely used throughout the worldGold is one of the worlds most precious metalsGold is the most malleable and ductile of all metals; a single gram can be beaten into a sheet of 1 square meter, or an ounce into 300 square feet.

Silver

•It has the highest electrical conductivity of all metals.•is a metallic chemical element with the chemical symbol Ag•Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.

Oxygen

•is the element with atomic number 8 and represented by the symbol O.

•a very pale blue, odorless, tasteless diatomic gas with the formula O2.

•Oxygen is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element

Zinc

The element was probably named by the alchemist Paracelsus

it has the symbol Zn and atomic number 30.

Various isolated examples of the use of impure zinc in ancient times have been discovered

•was discovered in 1898

•brilliant red color

•is the chemical element that has the symbol Ne and an atomic number of 10.

Uranium

•is a silvery-white metallic chemical element in the actinide series of the periodic table, with atomic number 92. It is assigned the chemical symbol U. A

•In nature, uranium is found as uranium-238 (99.2742%), uranium-235 (0.7204%),

•It occurs naturally in low concentrations

Potassium

•The USDA lists tomato paste, orange juice, beet greens, white beans, potatoes,

bananas and many other good dietary sources of potassium

•Potassium ions are an essential component of plant nutrition and are found in most soil types

•is the chemical element with the symbol K

Hydrogen

•The most common isotope of hydrogen is protium

•is the chemical element with atomic number 1.

•was first artificially produced in the early 16th century

Carbon•is the chemical element with symbol C and atomic number 6.

•best known are graphite, diamond, and amorphous carbon

• Diamond is among the hardest materials known

Chromium

•is a chemical element which has the symbol Cr and atomic number 24

•It is the first element in Group 6.

•It is also odorless, tasteless, and malleable

Aluminum•It has the symbol Al

•its atomic number is 13

•aluminum salts are not known to be used by any form of life.

Copper

•is a chemical element with the symbol Cu

•The metal and its alloys have been used for thousands of years

•Copper, silver and gold are in group 11 of the periodic table, and they share certain attributes

Nitrogenis a chemical element that has the symbol N, atomic number of 7 and atomic mass 14.00674 u

Nitrogen occurs in all living organisms

Many industrially important compounds, such as ammonia, nitric acid, organic nitrates

Helium is the chemical element with atomic number 2

it is the second most abundant element in the universe and accounts for 24% of the elemental mass of our galaxy

helium was observed on August 18, 1868

Lithium-6 is valued as a source material for tritium production and as a neutron absorber in nuclear fusion

is a soft, silver-white metal that belongs to the alkali metal group of chemical elements.

lithium are present in all organisms
