  1. What we did in class today: Thurs. Jan. 26th + Friday Jan. 27th + Monday Jan. 30th , 2012 Reviewed lab results and discussed the definitions and applications for mass, volume and density. Used the text to explore how the Periodic Table is a Map of the Elements. Topic Assessment over metrics and the parts of the atom. Completed study guide about Unit B Section 1.2 The Periodic Table is a Map of the Elements.

  2. Atomic # Number=Protons+Positive Carbon 6 C 12.01

  3. Nucleus/Mass = Protons + Neutrons Carbon 6 C 12.01

  4. -Electrons-Negative-Outside Carbon 6 C 12.01

  5. The Atoms Family The Atoms Family was created by Kathleen Crawford, 1994Presentation developed by Tracy Trimpe, 2006, http://sciencespot.net/

  6. The Atoms Family Story Name: Patty Proton Description: Positive Favorite Activity: Hanging out at the Nucleus Arcade Name: Nelda Neutron Description: Neutral Favorite Activity: Hanging out at the Nucleus Arcade In the center of Matterville, there is a place called the Nucleus Arcade, where two members of the Atoms Family like to hang out. Perky Patty Proton, like her sisters, is quite large with a huge smile and eyes that sparkle (+). Patty is always happy and has a very positive personality. Nerdy Nelda Neutron is large like Patty, but she has a boring, flat mouth and eyes with zero expression (o). Her family is very apathetic and neutral about everything. Patty, Nelda, and their sisters spend all their time at the arcade.

  7. 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)

  8. Topic Assessment • Label your paper with name, period and date. • Title your paper Metrics/Atom T.A. • #1-14 (multiple choice, true false or fill-in) • For #14 you will draw and label the parts of the atom. Include the following. • Nucleus • Energy levels • Proton (include the charge in words or symbols) • Neutron(include the charge in words or symbols) • Electron(include the charge in words or symbols)

  9. Unit B 1.2 Elements make up the periodic table. Pages 17-23 Directions: • Read your section silently to yourself. • As a group discuss what the section was about. • Write down a summary of your reading. Include any key vocabulary terms. • Create a poster that includes: • Section heading • Key terms w/ definitions • Summary notes • Picture example • Present info/poster to the class. • Others will take notes on your section. Time limit to be completed with group work: 15 minutes Groups: Pg. 17 Elements can be organized by similarities. Pg. 18 Mendeleev’s Table Pg. 19 Predicting New Elements Pg. 19 The periodic table organizes the atoms of the elements by properties and atomic number. Pg. 19 Reading the Periodic Table Pgs. 20-21 Decoding all the parts of the periodic table. Pg. 22 Groups and Periods Pgs. 22-23 Trends in the Periodic Table

  10. Elements can be organized by similarities. When the periodic table was organized by atomic number the elements also fell into columns and rows that have similar properties.

  11. Elements can be organized by similarities Mendeleev’s Table Predicting New Element He left blank spaces that were later filled by newly discovered elements. • Organized in rows by atomic mass. • 1st table in 1869.

  12. The periodic table organizes the atoms of the elements by properties and atomic number.

  13. The periodic table organizes the atoms of the elements by properties and atomic number. Reading the Periodic Table Groups and Periods Rows= Periods #1-7 Columns = Groups/Families #1-18 Atomic Number Chemical Symbol Element’s Name Atomic Mass Number

  14. Column =Group/Family ROW = Period #1-7 # of energy levels Label columns #1-18 Metalloids 1 Nobl e Gases Non-Metals 2 Metals 3 4 Transition Metals 5 6 7

  15. Trends in the Periodic Table

  16. Cross-out, change and highlight Unit B 1.2

  17. pr Protons, neutrons, electrons Are made of ATOMS Have a central nucleus Which contains Around which orbit Protons & neutrons electrons

  18. atomic mass properties repeating pattern of properties in the elements. The modern periodic table is organized by the atomic number and properties.

  19. Atomic number Symbol Name Atomic mass The element Rubidium has 37 protons. The vertical columns in the periodic table are called groups or families. The horizontal rows in the periodic table are called periods. As you move down the periodic table the atomic mass increases.
