The History of the Periodic Table Dmitri Mendeleev (1869) Rearranged some elements so that they would line up with other elements with similar chemical properties. Example: Tellurium & Iodine ***Probably won’t get to this on day 1.

The Periodic Table All of the elements in the same horizontal row on the periodic table make up a period.

The Periodic Table All of the elements found in the same vertical column make up a group or a family. Elements in a group have tend to have similar chemical properties

Textbook Hunt Elements in the same group have similar properties. There are four main groups we are going to be researching today: Alkali Metals, Alkaline Earth Metals, Halogens and Noble Gases.

Textbook Hunt Work with your elbow partner to complete the Textbook Hunt worksheet. Any of the information on this worksheet could be on your next quiz/test. We will go over this together in class!

1. What are columns on the periodic table called? Families/Groups 2. What are rows on the periodic table called? Periods 3. List two properties and two example elements of each of the following groups of elements: A. Alkali metals: Very reactive, first group B. Alkali earth metals: Less reactive, second group, form +2 charge C. Halogens: Used in neon lights, forms -1 charge D. Noble gases: full valence shell, not reactive 4. How did Mendeleev organize the periodic table? First by mass, then by chemical properties. 5. How is the current periodic table organized? By mass and chemical property.

Video Take note of: Characteristics of each group that makes it unique!

Examples of METALS Most metals are solids at room temperature (except for Mercury) Most metals are HARD (except Lithium, Potassium, Sodium) Other Examples: Copper, Aluminum, and Zinc

Physical Properties of METALS Metals have shiny luster. (or metallic luster) LUSTER – the way an object’s surface reflects light

Best conductors: silver and copper When you leave a spoon in a cup of hot drink, the bit poking out of the drink gets hot. Why? Conduction!! METALS are the best conductors of heat. Electrons in metals move more freely than in non-metals, allowing the heat energy to travel across the metal. For example, when the spoon touches the hot drink, the heat from the drink excites the electrons in the metal, and the electrons transfer the energy from one electron to another, carrying the heat all the way up the spoon quickly. Best conductors: silver and copper

Physical Properties of METALS Metals are good conductors of electricity. Copper, silver, and gold are good electrical conductors. In a conductor, electric current can flow freely. Since metals have free electrons, they can carry a charge easily. Copper Wiring

Physical Properties of METALS Metals are malleable. Malleable or Malleability - metals ability to be shaped or formed Ex: Aluminum is malleable.

Physical Properties of METALS Metals are ductile. Ductility or ductile – can be drawn into a wire

Chemical Properties of METALS Metals react with acids and can undergo oxidation (rust) Non-metals do not.

Chemical Properties of Metals Most metals have 3 or less valence electrons Most likely to LOSE electrons = Form cations  25

Non metals may be solids, liquids or gases. Examples of NONMETALS Non metals may be solids, liquids or gases. Examples: Solids – Carbon, Sulfur, Phosphorus Liquid – Bromine Gases – Oxygen, Hydrogen, Nitrogen

Physical Properties of NONMETALS Nonmetals have a dull luster. (They are not shiny!) Example: Phosphorus

Physical Properties of NONMETALS Nonmetals are insulators. They do not conduct electricity or heat well. The atoms in nonmetals do not have loose electrons. Therefore, when electricity, or something hot touches a non-metal, the energy does not move quickly through the material. What would you rather stir a hot pot with—a wooden spoon or a metal spoon?

Physical Properties of NONMETALS Nonmetals are soft (except for diamonds) and brittle. Example: Sulfur

Chemical Properties of Nonmetals Nonmetals have 5 or more valence electrons and usually gain electrons in chemical bonds = form anions. 30

An interesting nonmetal: Carbon Ever break the point of your pencil? That’s because it’s made of graphite, a substance made up completely of Carbon—a brittle nonmetal. Carbon atoms in graphite However diamonds, the hardest material of all, are made of the same element: Carbon. Look at how the carbon atoms are arranged in diamonds—why do you think diamonds are harder than graphite? You may also want to discuss how we are using carbon to create new materials such as nanotubes, or discuss buckeyballs.

The elements contained in the classification of Metalloids:

METALLOIDS Elements classified as Metalloids have physical properties of both metals and non-metals. Some are shiny, some are dull, they are somewhat malleable and ductile, and can conduct heat and electricity at a lesser level than metals. SILICON ARSENIC BORON

METALLOIDS Some metalloids are useful semiconductors, which are used in electronics (radio, computers, telephones, etc.) They are useful because they conduct just the right amount of electricity or heat.

Move to groups now!

Annotate Look over Model 1 quietly. Annotate any questions you have, patterns you notice, and note any information that jumps out at you and seems important. Be prepared to share your annotations with the class!

Electron Configuration Inquiry Work in the same groups as last time. Ms. Kline has handed you a role card. Write your role at the top of your page. The spokesperson may ask up to 3 questions before points are deducted from your group.

Exit Ticket Reflect: How well did your group work together? How well did each member of the group contribute? What changes need to be made for your group to finish all of your work tomorrow?
