<br> <center> 2022-2023 Review Homework for Electron Configuration, Atomic Mass and Periodic Table</center><br> <br> <u>Part I</u><br> Please provide the most appropriate answer in the space available.<br> <br> 1) If you have a list of subenergy levels (from closest to farthest), what does Aufbau Principle make you do to fill in electrons?<br> <br> 2) What subatomic particle does Pauli Exclusion deals with?<br> <br> 3) Define Hund's Rule ______________________________________________________________<br> <br> ____________________________________________________________________________________<br> <br> <br> 4. How many subenergy levels (and what are their designation) in the 3rd energy level?<br> <br> 5) How many orbitals are in a "d" subenergy level?<br> <br> 6) electrons will fill the 2nd energy level? _____________________<br> <br> 7) Can you have a 3f subenergy level ? Explain you answer. <br> <br> <br> 8) 11. Define isotope and give the three different symbolic representation of an isotope (use Carbon with 7 neutrons as example).<br><br> _________________________________________________________________________<br> <br> 9) #n (neutrons) = ____ - _____<br><br> <br> 10) Circle the one that is located on the Periodic Table: Atomic Number or Mass Number. <br> <br> 11) Define Valence electron and how can you find from the Periodic Table.<br> <br> 15. Define atomic mass.<br> <br> <br> <u>Part II</u><br> Write the electron configurations for the following elements. Give # of valence electron. If element is a "d" or "f" block element, write NA.<br> <br> 1. As (Arsenic) <br> <br> <br> <br> 2. Bi (Bismuth)<br> <br> <br> <br> 3. Cs (Cesium)<br> <br> <br> <br> <br> <br> <u>Part II</u><br> <br> Give the #p,#n and #e for the following isotopes:<br> <br> a. Ca-42<br> <br> b. C-13<br> <br> c. U-238<br> <br> <br> <u>Part III</u><br> After printing out the tables in [http://www.tmcleod.org/Level1/0809twotableforatomicmasscaltable.doc Two Calculating Atomic Mass Table], use the information from your table of isotopes to calculate the atomic mass of sulfur and oxygen. <br> <br> <br>
