In this activity, students will investigate basic electron structure by making a model of the electron structure using pennies representing electrons in different sized filter papers to represent energy levels, for an atom or ion, at various workstations. Students will place the pennies (electrons) in the appropriate energy levels, and record the number of electrons in each energy level on a data table.
This simulation provides practice in building Lewis Dot Structures from atoms and ionic compounds from the component ions.
In this activity, students use a map of electron configuration (patterned after the Bohr model) and round markers (bingo chips or other similar object) to configure electrons for assigned elements.
This website discusses Niels Bohr and his journey on his proposed model for the atom.
In this lesson, students will draw electron dot diagrams for atoms and Lewis diagrams for molecules; students will also define single, double, and triple covalent bonds as well as polyatomic ions and their Lewis diagrams.
An interactive periodic table that provides not just the basic information, but also information about where the element can be found and how it is used.

This worksheet provides students practice in determining electron energy levels.
This TEDTalk discusses atomic structure and subatomic particles, specifically as related to the location of electrons. Discussion and other assessment questions are provided to extend the thinking.
This lesson will help students grasp the relationships among protons and electrons, locations of various elements, electron energy levels, and oxidation numbers. Students will draw and analyze electron energy level diagrams and then determine the oxidation number based on their diagrams.
In this lesson, students roll dice in order to simulate the probability of locating an electron in a certain region around the nucleus.
Students will write the electron configuration for various elements, given the atomic number. Given the location of an element on the periodic table, students will be able to give the highest energy level the valence electrons are on, and how many valence electrons it has.
