Organization of the Periodic Table

On the back of your handout, create a METALS section On the back of your handout, create a METALS section. Draw the Chart below: Physical Property Yes No Brittle Conductor Ductile Insulator Luster (shiny) (dull) Malleable Using the examples of metals on your table, perform the tests in the chart above. Record your findings in the chart.

Your chart should look like… Physical Property Yes No Brittle Conductor Ductile Insulator Luster (shiny) (dull) Malleable 2 Video Clips: Conductor and Ductile Most elements are metals. Metals are found on the LEFT side of the periodic table. Click on the Gold Bar to view a VIDEO CLIP ON: METALS

Outline your METALS on the Periodic Table:

Iron, Cobalt, & Nickel are the only metals that are magnetic! Mercury is a metal that exists in liquid form at room temperature. The most expensive metal is rhodium, which sells for more than $176,000 per kilogram. The symbol used for silver is Ag, this comes from the Latin word argentum. Sodium, potassium, rubidium, caesium, and francium are extremely reactive elements, just putting them in water can cause an explosion! An alloy is a metal made by combining two or more metals. Bronze is a metal alloy made from copper and tin. Steel is a metal alloy made from iron and carbon. Did You Know?

WARM-UP Tuesday (9/23) (live oak) HINT: D = M÷V D= 660 ÷ 750 D = 0.88 g/cm3 (live oak)

Add a NON-METALS section on the back of your handout Add a NON-METALS section on the back of your handout. Draw the Chart below. Physical Property Yes No Brittle Conductor Ductile Insulator Luster (shiny) (dull) Malleable Using the examples of non-metals on your table, perform the tests in the chart above. Record your findings in the chart.

Your chart should look like… Physical Property Yes No Brittle Conductor Ductile Insulator Luster (shiny) (dull) Malleable Non-metals like to combine with metals to form completely new compounds. Non-Metals are found on the RIGHT side of the periodic table. The link should only play clip 13 (click on 13 if it tries to play the whole thing) Click on the Sulfur Sample to view a VIDEO CLIP ON: NON-METALS

Outline your NONMETALS on the Periodic Table:

Diamonds and graphite (pencil lead) are both made up of carbon, but have very different properties. Hydrogen is the only non- metals on the left side of the periodic table. Helium is lighter than the air around us so it floats, which makes it perfect for balloons. Nitrogen gas is used in food storage to keep packaged foods fresh. Hydrogen is the most common element found in our universe. Bronze is a metal alloy made from copper and tin. Some tree frogs use a poisonous chlorine compound in their skin. Did You Know?

WARM-UP Wednesday (9/24)

ADD a Metalloids section on the back of your handout ADD a Metalloids section on the back of your handout. List this information: Metalloids are solids. They share some physical properties with metals and some physical properties with nonmetals. They can be semi-conductors, meaning they may be able to conduct a little electricity or heat.

Metalloids (cont’d.) They are found along the stair- step line or the zig-zag line on the periodic table. There are 7 – Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, and Polonium. Click on the Silicon Sample to view a VIDEO CLIP ON: NON-METALS

Outline your METALLOIDS on the Periodic Table:

Silicon and Germanium are semiconductors that are used in computer chips. Metalloid comes from the Greek and. means “sort of metals” Arsenic can be yellow, black, or gray and was known for many centuries as the “King of Poisons”. Marie Curie named Polonium after her homeland, Poland. Silicon is the most common metalloid and the second most common element in Earth’s crust. Boron is used to control nuclear reactions. Antimony was used in some countries as eye makeup. Did You Know?

Physical Properties : VOCABULARY Brittle – Matter that breaks easily when bent or shatters is said to be brittle. Luster (shiny or dull) – The way matter reflects light from its surface is called luster. Matter that reflects a large amount of light is called shiny. Matter that reflects little light from the surface is called dull. Malleable – Matter that can be hammered or rolled into thin sheets without shattering is said to be malleable. Ductile - . Matter that can be pulled or stretched into thin wires is said to be ductile. Conductor – Matter that allows electricity and/or heat to flow through it easily is called a conductor. Insulators - Insulators do not allow the electricity to pass through easily.
