Tired of blowing up countless balloons to illustrate orbital shapes around an atom? Give your lungs a break and use an interactive instead! Learners observe s, p, d, and f orbitals through the first four energy levels using hydrogen as a...

When molecules of hydrogen and oxygen are combined, how does water form? Science scholars observe changes in kinetic and potential energy during a chemical reaction in an interactive. The resource features easy controls that allow users...

I don't trust atoms because they make up everything. Budding scientists learn about famous scientists connected to atomic models, chemical, ionic, and hydrogen bonds. The presentation also presents how to count atoms...

It's molecule magic! Skillful scholars explore the effects of different atoms on molecular polarization using an intuitive interactive. The resource displays the charge at different locations on the molecule, then adapts as the user...

Learners practice drawing Lewis dot structures, build molecules with model kits, and predict molecular shapes using VSEPR theory. The combination of written work and hands-on reinforcement benefits young scientists.

Resource investigates how Bohr's model of hydrogen explains atomic emission spectra.

An explanation of Niels Bohr's (1885 - 1962 CE) Model along with an app that illustrates a hydrogen atom according to the particle or wave model. You can choose a principal quantum number "n." The right part of the graphic represents the...

Tutorial provides a discussion of UV-Vis spectroscopy, infrared (IR) spectroscopy, and the Beer-Lambert law.

Article explains the experiments on the photoelectric effect and how these experiments led to the idea of light behaving as a particle of energy called a photon.
