![]() ![]() What is the relationship between the "block'' size and the number of electrons that will fit in the corresponding atomic sublevel? An s sublevel can hold 2 electronsthe ''sblock" has 2 columns. Count the number of columns in each of the four "blocks" of the table in Model 1. ![]() You just need a few data points in each section to answer the questions that follow. It is NOT the goal of this activity to fill in the entire periodic table. Talk to at least one team from each of the "blocks" (i.e., you want to look at a set of elements in the sblock, clblock, pblock, and fblock). ![]() Add the last orbital notation for their groups of elements to Model 1. Read This! Go on a searchsend a representative of your group to other tables to find out what they have discovered in Questions 14. For Team ], the element configuration ends with an s sublevel in the energy level that matches the row number. What is the relationship between the last orbital notation in your set of ground state electron configurations and the row numbers on the lefthand side of the periodic table in Model 1? Answers will vary for each team. For Team 1, the element configuration ends with one electron in the s sublevel and the set of elements is found in the first column of the sblock. What is the relationship between your answer in Question 2 and the "block'' of the table where your set of elements is located? Answers will vary for each team. Write the last orbital notation in the electron configuration for each element in your set in its respective box. Locate where your set of elements should be in Model 1. For Team], the configuration always ends in s 1.ΔΆ 3. What is similar about the last orbital notation appearing at the end of the configuration for each element in your set? Answers will vary for each team. H ls1 Na 3s1 Rb 5s1 Li 2s 1 K 4s 1 Cs 6s1 2. For each element on your card, write the last orbital notation appearing at the end of the configuration (the underlined portion). Record your team number 1 and team name Alkali metals b. Obtain a card with electron configurations for your group as assigned by your teacher. In today's activity, you are going to study how the ground state electron configurations and structure of atoms are related to the shape and organization of the periodic table. Those properties relate to the electronic structure of the atoms of each element. The periodic table is organized by properties, both chemical and physical. But to a chemist, the periodic table is a very powerful tool. It's not organized alphabetically so elements can be found easily. Large portions of the table appear to be missing at the top. 1 Why? Cracking the Periodic Table Code Why aren't the elements listed in alphabetical order? As charts go, the periodic table is a bit odd. ![]()
