Name: Annie Boredaam Date: Oct,15,2020 Student Exploration: Electron Configuration Directions: Follow the instructions to go through the simulation. You can determine the ground-state electron configuration of Selenium (Se) by locating the position Se in the periodic table. Boiling point The temperature at which the liquid–gas phase change occurs. What we will do now is place those electrons into an arrangement around the nucleus that indicates their energy and the shape of the orbital in which they are located. The electronic configuration of an atom can be predicted from its atomic number. In the case of Cesium the abbreviated electron configuration is [Xe] 6s1. Here is your Free Content for your Lesson on Electron Configuration! To do this, we count for the number of electrons to be distributed. The electronic configurations of atoms help explain the properties of elements and the structure of the periodic table. 2) Set the permission of your Google Doc to “ Anyone with the link can view ”.
