cracking the periodic table code answer key

Nunnelee Room: JMASC Room 215 Phone: 91 ext.ģ215 e-mail: (school) (home) Textbook: Chemistry, by Zumdahl, 9th ed., Cengage, 2014. Pre-AP Chemistry 2015-2016 Instructor: Mrs. Cut out the sectionsas instructed and reassemble the periodic table sequentially by atomic number. Obtain from your teacher the Periodic Table handout and a pair of scissors. Why then does the “d-block” start in the fourth row of the periodic table?9.įor the elements of the “d-block” how is the row number related to the principal energy level for the last orbital notation of their electron configurations?10. The third energy level in an atom contains a d sublevel. Pogil Activities For High School Chemistry Cracking The Periodic Table Code Answers Why does the second row of the periodic table not have a “d-block” section?b. Work your way up the Electron Energy Levels diagram, locating as many sublevel sections as youcan on Model 1.a. Whyare there only two elements in the first row of the periodic table?8. Start at the bottom of the Electron Energy Levels handout with the 1senergy sublevel and locate the section of the periodic table corresponding to that sublevel. Put the Electron Energy Levelshandout next to Model 1. Obtain the Electron Energy Levels handout from your teacher. What is the relationship between where an element is located within a “block” of the table inModel 1 and the superscripted (raised, like an exponent) value appearing at the end of theelectron configuration for that element?2 POGIL Activities for High School Chemistry 7. What is therelationship between the “block” size and the number of electrons that will fit in the correspondingatomic sublevel?6. Count the number of columns in each of the four “blocks” of the table in Model 1. You just needa few data points in each section to answer the questions that follow.5. It is NOT the goal of this activity to fill in the entire periodic table. Talk to at leastone team from each of the “blocks” (i.e., you want to look at a set of elements in the s-block, d-block,p-block, and f-block). What is the relationship between the last orbital notation in your set of ground state electronconfigurations and the row numbers on the left-hand side of the periodic table in Model 1?Read This!Go on a search-send a representative of your group to o ther tables to find out what they have discoveredin Questions 1–4.Īdd the last orbital notation for their groups of elements to Model 1. What is the relationship between your answer in Question 2 and the “block” of the tablewhere your set of elements is located?4. Write the last orbital notation in the electron configuration for each element in your set in itsrespective box.b. Locate where your set of elements should be in Model 1.a.
