  1. Periodic Table SC.8.P.8.6 Recognize that elements are grouped in the periodic table according to similarities of their properties.

  2. SC.8.P.8.6 Recognize that elements are grouped in the periodic table according to similarities of their properties.

  3. Which describes how elements are arranged in the periodic table? • A. by increasing atomic mass • B. by increasing atomic number • C. by chemical name • D. by chemical symbol

  4. Objective • Today I will complete my test in mixtures. • So that I can demonstrate my gains on bench march SC.8.P.8.9 on mixtures • I know I have it when I can pass my test11 out of 15.

  5. Mixture 1 SC.8.P.8.9 • C= 0 • H= none • A= Test • M= none, I will collect test • P=Looks like students writing down school wide heading and bubbling I.D. number. Set folders up and don’t write on test. Wait until test has been picked up./When finished wait for further directions • S=11 out of 15

  6. Objective (SC.8.P.8.6) • Today I will cite evidence that supports the organization of the periodic table. • So that I can explain how elements are grouped in the periodic table. • Explain how the periodic table was arranged in the past and also currently. • I know I have it when I have cited the evidence of the history of the periodic table by answering questions and completing my 4 square. • I can answer 3 out of the 4 questions using cards up.

  7. Champs (Cite Evidence) • C= 2 with group but level 0 when either debrief by teacher or student shares. • H= ask 3 before me • A= Citing Evidence • M=none or stand up, hands up pair up • P= Looks like students citing evidence and completing 4 square). Looks like students sharing during Kagan strategy. • S= Check for success.

  8. Organizing the Elements (p.285) • How do you organize your clothes in your closet? • What is something important for you to organize, why? • Organizing things usually makes them easier to use because you can better know their properties, or characteristics c. Determine the central idea of the text. • The central idea is how scientist organize elements by a set of patterns.

  9. Mendeleev’s Work paragraph #1 (Text p. 286) • What did Mendeleev know about elements? • Elements had similar chemical and physical properties. 2. In order to find patterns and hidden clues what did Mendeleev note? • Mendeleev noted the melting point, density and color of the elements. 3. What information did he also include to support this pattern? • Mendeleev included atomic mass. 4. What example did he provide supporting this pattern? • He noted silver and copper are both shiny metals

  10. Mendeleev’s Work Paragraph #2 (Text page 286) 5. What does it mean by an element’s atomic mass? • Atomic mass determines the mass of the element as well as their isotopes. 6. When Mendeleev arranged the elements in order of increasing atomic mass what did he notice? • Mendeleev noticed after arranging the elements in order of increasing atomic mass that patterns of properties existed.

  11. Mendeleev’s Work Cite Evidence 7. Cite several pieces that support Mendeleev’s belief that the Periodic Table contains hidden clues that create a pattern. • Mendeleev noted that elements had similar chemical properties and physical properties. • For example silver and copper share properties in both being shiny. • He also noted close similar pattern in melting point, density and color. • He also included the element’s atomic mass. • He noted when arranging the elements by increasing atomic mass he found that the pattern of the properties repeated regularly.

  12. Periodic Table (page 286) Define Periodic Table Detail 1 The atomic number is related to the chemical Property which helped arrange the periodic table Chart showing all of the elements Arranged according to repeating Pattern of their properties Example Detail 2 For example bromine, chlorine and Iodine have similar properties so they are grouped together. Mendeleev created the first periodic table by atomic mass

  13. Compounds are pure substances made from two or more elements chemically combined. What is the name of the illustration that shows all the known elements? • A. element table • B. periodic table • C. star chart • D. solar system model

  14. Ted wants to know the average atomic mass of calcium. He knows that the letters Ca stand for calcium. He found the entry for calcium, Ca, in Period 4 of the periodic table. The diagram below shows this entry. • Which of the following numbers should Ted identify as the average atomic mass of calcium, Ca? • A. 4 • B. 20 • C. 40.078 • D. 60.078

  15. What do elements in the same group on the periodic table have in common? • A. They have similar chemical symbols. • B. They have the same atomic number. • C. They have similar chemical properties. • D. They have the same average atomic mass.

  16. Each element has an average atomic mass. Why is it called an “average” atomic mass and how is it determined? • It is called an average atomic mass because an element can have different isotopes. Each isotope has a different number of neutrons in its nucleus. Therefore each isotope has a different atomic mass.

  17. In each square on the periodic table, there are usually four pieces of information concerning each element. Explain what each piece of information is. • The atomic number is located at the top and • Identifies it property • states umber of protons which equals number of electron Chemical symbol is located here This is the chemical name The bottom number is the atomic mass which is the number of protons plus the neutrons.

  18. Objective (SC.8.P.8.6) • Today I will cite evidence that supports the organization of the periodic table. • So that I can explain how elements are grouped in the periodic table. • Explain how the periodic table was arranged in the past and also currently. • I know I have it when I have cited the evidence of the history of the periodic table by answering questions and completing my 4 square. • I can answer 3 out of the 4 questions using cards up.

  19. Champs (Cite Evidence) • C= 2 with group but level 0 when either debrief by teacher or student shares. • H= ask 3 before me • A= Citing Evidence • M=none or stand up, hands up pair up • P= Looks like students citing evidence and completing 4 square). Looks like students sharing during Kagan strategy. • S= Check for success.

  20. Using the Periodic Table (text page 287) • When using the periodic table list the 4 key information found in each square.

  21. Ted wants to know the average atomic mass of calcium. He knows that the letters Ca stand for calcium. He found the entry for calcium, Ca, in Period 4 of the periodic table. The diagram below shows this entry. • Which of the following numbers should Ted identify as the atomic number of calcium, Ca? • A. 4 • B. 20 • C. 40.078 • D. 60.078

  22. Objective • Today I will examine craft and structure by looking at the meaning of symbols and terms in the periodic table. • So that I can explain the reason elements are grouped in the periodic table by their properties • Identify the families and groups in the periodic table. • I know I have it when I completed by periodic table by labeling and coloring it. • I can answer correctly 70 percent of question during the “hold cards up” task.

  23. Periodic table SC.8.P.8.6 • C= 0 when debrief and 2 with group • H= none • A= Craft and structure identify terms and symbols • M= none • P=Looks like students writing down notes and color coding periodic. (2) Parent Share (3) Keeping cards down and picking card up when listing to the bell. • S=completing periodic table and answering 70 percent of questions presented.

  24. Alkali Metals Alkaline Earth Metals Transition Metals Lanthanides Actinides

  25. Noble gas Carbon Nitrogen oxygen Halogen Boron Metalloids

  26. Bell Work Week 7 #4 • Elements are classified as metals, nonmetals, and metalloids because each of those types of elements has common properties. Where are the most nonmetals found in the periodic table? • A. inthe 5 far right columns • B. in the middle 10 columns • C. in the bottom 2 row • D. in the 2 far left columns

  27. Notes Periodic Table • Groups/families are in columns • Periods go across in rows and there are seven. • Alkali groups are the most explosive because they easily react, they tend to give away their valence electron.

  28. Links Alkali Reactions • https://www.youtube.com/watch?v=m55kgyApYrY • https://www.youtube.com/watch?v=qliI4LXdqpQ • Metals are the most abundant on the periodic table • Noble gas don’t want to react to any element because the energy level is completely full. • You will find the metalloids on the heavy line.
