1 Identify how elements are arranged on the Periodic Table. The periodic table is arranged by ____________ which makes elements with similar __________________ be near each other

2 1st Verse: They’re tiny and they’re teeny, Much smaller than a beany, They never can be seeny, The Atoms Family. Chorus 2nd Verse: Together they make gases, And liquids like molasses, And all the solid masses, The Atoms Family Chorus 3rd Verse: Neutrons can be found, Where protons hang around; Electrons they surround The Atoms Family. Chorus Chorus: They are so small. (Snap, snap) They’re round like a ball. (Snap, snap) They make up the air. They’re everywhere. Can’t see them at all. (Snap, snap)

7 1.The black zigzag line… separates the metals from the non metals. 2._____ elements are gases? 3._____ elements are liquids? 4. Most elements are solid __________. 5. A “group” of elements, 6. A “period” is… 7. There are ____ nonmetals? 8. There are ____ metalloids? Name: Date: Period: Read pages to answer these questions: 11/12 2 metals also called a “family “ found in columns. They share similar properties. a horizontal row with atoms having the same number of rings. 17 8

8 Element Properties Work with your partner to match the properties with the correct definition on the “Properties of Elements” worksheet. GO ON

9 On the Inside BY YOURSELF complete BOTH sides of the “On the Inside” worksheet. You do NOT have to draw the Oxygen Atom GO ON

11 Interactive Periodic Table Game CLICK ON PICTURE:

12 ___Ductile ___Malleable Able to be pulled into a long wire c d Able to be hammered or rolled into a shape ___Brittleg Easily broken and is not able to be molded or shaped ___ Conductor of electricity k Allows electricity to flow freely

13 ___ Conductor of heat ___Dull Allows heat to flow freely l n Not shiny ___Softm Not hard ___Shiny i Lusterous

14 ___ high boiling point ___ High melting point Boils at a high temp. so is usually a liquid at room temperature h j Melts at high temp. so is usually a solid at room temperature ___ Semiconductor f Will carry electricity only under certain conditions ___Opaque a Not clear or transparent

15 ___Density ___Reactive b e Will quickly & easily combine with other elements D=M÷V, determines is it will sink or float

16 Periodic Table of Elements

17 Creating New Elements Click the picture below to view a NOVA video clip about scientists working to create new elements.

18 Melting Points in a Group of Elements 1. Work with your partner to read the graph on the following 4 slides and answer the questions. 2. Record your answers on the worksheet. Each student should have there own paper. Complete Scavenger Hunt using next slide.

20 Melting Points in a Group of Elements –Melting points decrease from lithium to francium. ANSWERS: Click to see answer below. –As you look at Group 1 from lithium to francium, describe how the melting points of the alkali metals change. - Metals 1.

21 Melting Points in a Group of Elements –New element 119 should have a melting point of approximately 25ºC. ANSWERS: Click to see answer below. –If element number 119 were made, it would fall below francium in Group 1 of the periodic table. Predict the approximate melting point of new element Metals 2.

22 Melting Points in a Group of Elements –None of the alkali metals are liquids at room temperature. –Cesium and francium might melt if you could hold them in your hand. ANSWERS: Click to see answer below. –Room temperature is usually about 22ºC. Human body temperature is 27ºC. Which of the alkali metals are liquids at room temperature? –Which might melt if you could hold them in your hand? - Metals 3. 4.
