Complete Electron Configurations - Directions
Using the Complete Electron Configurations Concept Builder is quite simple. There are three difficulty levels in all. All three difficulty levels work the same way. You are given the name and symbol of a neutral atom (Apprentice and Master Difficulty Level) or of a charged ion (Wizard Difficulty Level) and you must identify the correct electron configuration corresponding to the atom or ion. There are always five options to choose from. You can select an option by tapping on the electron configuration (or upon the radio button to the left of the configuration). Doing so will hilight the option and reveal the Check Answer button. If you are satisfied with your answer, then tap on the Check Answer button. Your answer will be evaluated and your Progress Report will be updated. If you are not certain of your choice, then you can deselect it by tapping on it a second time or simply tap on a different option to select it instead.
Your goal is to earn "Stars" and to complete one or more difficulty levels. Stars are earned when you show success on a particular question. Once you show success on all the questions for a particular difficulty level, you will earn the trophy for that level.
