Transcript of Families of the Periodic Table

The Periodic Table Background Information Alkaline Earth Metal Family Halogens The Noble Gases Rare Earth Metals Family Barium, Beryllium, Calcium, Magnesium, Radium, Strontium Aluminum, Cesium, Francium, Lithium, Potassium, Rubidium, and Sodium are all in the Alkali Metal Family The Halogens are a combination of solids, liquids and gases. The solids are Iodine and Astatine, the liquid is Bromine, and the gases are Fluorine and Chlorine Helium, Neon, Argon, Krypton, Xenon, and Radon Dmitri Mendeleev was a Russian chemist who founded the Periodic Table of Elements. The Periodic Table was made to organize all known elements into a simple chart while leaving space for new components to be added later. Commonalities
Quite nonreactive
Have a full valance shell
Low boiling points High luster, but tarnish readily in air
Silver, silvery-white, or gray metals.
High electrical conductivity Argon-light bulbs
Neon-advertising signs
Helium-to fill airships and weather balloons Real Life Uses Promethium- nuclear batteries
Holmium- lasers
Thulium- portable x-ray machines Commonalities Real Life Uses Calcium- found in milk Barium- used for green fireworks Radium- Cancer Treatment Samarium Alkali Metal Family Transition Metals Commonalities Real Life Uses Commonalities Lower densities than other metals
One loosely bound valence electron
Largest atomic radii in their periods High melting points, boiling points, and electrical conductivity
Low ionization energies
Very hard, yet still malleable Commonalities Real Life Uses Rubidium-used in vacuum tubes
Cesium-radiation therapy
Sodium-table salt Very reactive.
Can bond with many other elements
Are all electronegative (the tendency of an atom to attract electrons) Fluorine-used in rocket fuels due to its reactive nature.
Chlorine-used to make pools clean
Bromine-used for flameproof agents Commonalities Real Life Uses Zinc Everyday Uses Copper- cookware, electrical wiring
Titanium- bone implants
Manganese- ores used in the production of steel most reactive metals
characterized as being extremely soft and silvery in color
lower densities than other metals By: Kaleb Salas, Minjoon Choi, Umesh Narayan TROLOLOLOL! bnklgsad;mkla
