Students participate in an Electron Square Dance in which they act the part of atoms. They follow the structure of different atoms suggested by the teacher.

In this elements instructional activity, students write the electron configurations for given elements. Students describe ionization energy and electron affinity and the periodic trends for both. This instructional activity has 20 short...

Fourth graders compare electricity and magnetism. In this science instructional activity, 4th graders discuss the concepts of electricity and magnetism and brainstorm examples of electrical and magnetic forces.

Students investigate the atom and how it is formed. They conduct research using a variety of resources and then construct a model of the atom. Then students have class discussion. The lesson includes background information for the...

Students discuss the mass-energy relationship based on Einstein's work. They calculate the energy released in various scenerios and sketch diagrams for the Lyman, Balmer and Pfund Series. In groups, they discuss the role of photons and...

Explains the creation of hybrid orbitals and presents their electron density plots and energy diagrams. Requires Java.

This simulation explores the trends observed in orbital energies for the main group elements of atomic orbital energies.

Using a Java applet, sets of atomic orbitals are compared with different quantum numbers in order to compare the orbital sizes.

This article is provided by Florida State University. Schroedinger wave equation is explained and how quantum numbers are used to describe the energy level of any electron in an atom. The relationship of atomic orbitals to quantum...

The Bohr model and atomic orbitals. Using an element's position in the periodic table to predict its properties, electron configuration, and reactivity.

Introduces learners to atomic models of the past and present, focusing on the orbital model and an explanation of its basis. Learners then have the opportunity to "make an atom" and contrast it with an ion, followed by an isotope. The...

Explanation of advanced atomic theory using The Schrodinger equation.

This site from the Purdue University provides an overview of atomic orbitals and how quantum numbers specify these orbitals. Includes a model that can be rotated and examined in 3D. Includes learning exercises and answers.

The website provides an explanation of the electrons' position in their orbitals as they spin around the nucleus. Quantum theory is also explored by explaining that the exact location of a specific electron is a not exact but a guess.
