Code Makers - Electron Configuration, Aufbau Principle

In this electron configuration learning exercise, students write the electron configurations of 22 elements and compare their valence electron configurations. They list the elements that are similar in terms of their electrons. They...

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on an entire year's curriculum when they take this thirteen page test. 

Sixty multiple choice questions cover the entire gamut of chemistry concepts. This is the local section of the U.S. National Chemistry Olympiad, where your chemistry candidates take a shot at entering the national competition. They...

National Chemistry Olympiad tests are released after their use each year, since they cannot use them again for this event. The result: outstanding comprehensive assessment resources for general chemistry classes! This 2005 version covers...

Delve into the world of quantum mechanics by viewing this PowerPoint. Chemistry novices learn about electron energy and shells, and they practice listing electron configuration for different atoms. Because this presentation provides...

The creator of this collection of chemistry slides is clever! Electron configuration is explained as, click-by-click, orbitals are displayed and then each is subsequently filled with the proper amount of electrons. After the progression,...

Electrons don't really exist as particles in an atom, but more as waves which move at different frequencies. Explore electron configurations through learning about their shells and orbitals and how this relates to the periodicity of the...

A simple analogy helps to explain a complicated concept in this instructional chemistry video. After first listening to a description of a hotel with different types of rooms on different floors, each with its own...

Demonstrate the steps to drawing electron configuration diagrams. A video lesson shows how to use the periodic table to determine the number of electrons in an element and then create the diagrams. The instructor leads your class through...

Acting as a subtopic of the General Chemistry Virtual Textbook's section on Atoms and the Periodic Table, this site discusses a series of topics related to electrons including atoms that have only one electron, effects of...
