An Electron's Address
Where does an electron reside? Chemistry scholars determine an electron's "address," that is, what orbital it can be found in. This resource is both instructional and practical, providing a thorough explanation of energy levels and...

Unit 2 ~ Atomic Structure
As an atomic structure reference and review tool, this handout fits the bill. The first page provides definitions and tables of orbitals, electrons, and energy levels. The second page is an opportunity to practice determining numbers of...
Curated OER
Elements, Atoms, Ions, and the Periodic Table
This PowerPoint provides a complete recap of all the information needed for a unit on elements and the periodic table. The seventy slides cover the basic notation of elements, energy levels and ionization energies. The trends in the...
Curated OER
Where are the Electrons?
In this electrons worksheet, students complete a graphic organizer to show the pattern of the principal energy levels, number of orbitals, and electrons in each sublevel of atoms.
Curated OER
Energy Levels and Electron Configurations
Twelfth graders investigate the proper filling order of electrons in the energy levels of an atom. They practice how to "read" these occupied energy levels as electron configurations and demonstrate their understanding through creative...
Curated OER
Location of Electrons
In this location of electrons worksheet, students read about the quantum mechanical model of the atom and the location of electrons. They complete a table given eleven elements with the sublevel notation, the Bohr notation and the...
It's About Time
Atoms with More Than One Electron
Provide young chemists with the ability to manipulate atoms and predict their results, in this sixth lesson. Pupils analyze energy patterns as they predict the amount of energy required to remove electrons from atoms. They compare trends...
Curated OER
Electron Configurations and Orbital Diagrams
In this elements worksheet, students determine the electron configuration, orbital diagram for the highest sublevel, and the number of unpaired electrons in ground state atom for the given elements. This worksheet has 7 problems to solve.

Electrons in Atoms
Electrons could never be Bohring! The presentation covers where you find electrons in an atom. It begins with the Bohr Model, then moves on to the Heisenberg Principle and orbital shapes. It concludes with the concept of electron spin...
Virginia Department of Education
Atomic Structure: Elements
It's all relevant, really. Individuals use the scientific method to learn more about elements, atoms, and their placement on the periodic table. They conduct experiments using materials common in nature to explore how elements affect our...
Curated OER
Electron Arrangement in Atoms
In this electron configuration worksheet, students fill in 10 blanks with the appropriate terms, they determine if 6 statements are true or false, they match 5 terms with their meanings and they answer two questions about electron...
