periodic?• A:

HISTORY OF THE PERIODIC TABLE

• Dmitri Mendeleev (1869) – Russian Chemist and Teacher– Created 1st organized Periodic Table ≈ 63

Elements

• 1. Cue cards with descriptive information about each

• 2. Ordered cards according to

• 3. Grouped Elements with

• 4. Undiscovered or “missing” Elements created problems.

• 5.

HISTORY OF THE PERIODIC TABLE• Henry Moseley

– Researched with Rutherford

•

Modern Periodic Table

• The Elements are arranged according to

• Valence Electrons:

• GROUP: “FAMILY”

• Elements contained in them have similar properties b/c……

Modern Periodic Table

• PERIOD:

• ***Special Note***

METALS• Properties of Metals: • Why can they conduct? Why

are they malleable and ductile? WHY???????????????

REPRESENTATIVE GROUPS ALKALI METALS

• GROUP #1: • Alkali Metals• Very Reactive due to 1

Valence Electron• Found in nature only in

compounds• Form Salts (NaCl, KI)• Very soft, low

densities, low melting points

• USES:• Lithium:• Lithium hydroxide = Batteries• Lithium Carbonate = treatment

for manic depression• Francium = very unstable• K, Rb, Cs react with great

violence• Hydrogen: • Set apart from the table b/c it

reacts like a metal and nonmetal. Largest use is in the production of Ammonia NH3

REPRESENTATIVE GROUPS ALKALINE METALS

• GROUP #2:

• ALKALINE METALS

• Reactive due to 2 Valence Electrons

• Found in nature only in Compounds

REPRESENTATIVE GROUPS ALKALINE METALS

• ALKALINE METALS USES• Magnesium: Magnesium Chloride = Milk of Magnesia• CALCIUM: CALCIUM COMPOUNDS = BONES

– Fact: As you get older your bodies ability to take Ca out of food decreases so your body starts using Ca from the from the Bones. Leaving Pin holes. “Osteoporosis”

– Calcium Chloride = de-ice roads– Calcium Carbonate = Limestone, Chalk, Shells

• Beryllium: lightest, rare, strong, high melting point• Used in anti-spark tools, mixed with Copper to make alloys

that conduct and are wear resistant.

REPRESENTATIVE GROUPS TRANSITION METALS

• GROUP 3 THROUGH 12:

REPRESENTATIVE GROUPS RARE EARTH METALS (UNSTABLE)

• LANTHANIDE SERIES: (58-71)

• USES:

• ACTINIDE SERIES: (90-103)

NONMETALS

• PROPERTIES OF NONMETALS:

METALLOIDS

• Properties of Metalloids:

REPRESENTATIVE GROUPS BORON GROUP

• BORON: Metalloid

• ALUMINUM: Metal

REPRESENTATIVE GROUPS BORON GROUP

• Carbon: Nonmetal

• Silicon: Metalloid

• Tin: Metal

• Lead: Metal

REPRESENTATIVE GROUPS NITROGEN GROUP

• Nitrogen: Nonmetal

• Phosphorus: Nonmetal

• Arsenic: Metalloid

• Antimony: Metalloid

• Bismuth: Metal

REPRESENTATIVE GROUPS OXYGEN GROUP

• Oxygen: Nonmetal

• Sulfur: Nonmetal

• Selenium: Nonmetal

• Polonium: Metalloid

REPRESENTATIVE GROUPS HALOGENS

• Fluorine: most reactive Nonmetal

• Chlorine: Nonmetal, green gas

• Bromine: Nonmetal

• Iodine: Nonmetal

REPRESENTATIVE GROUPS NOBLE GASES

*****HYDROGEN*****

• Fusion is the joining of two light nuclei to produce a heavier one. Mass is lost and a tremendous amount of energy is released (even more than the energy released in nuclear fission). Solar energy is a form of fusion energy. When two isotopes of hydrogen combine at very high temperatures, fusion occurs. A diagram of nuclear fusion is shown below
