Lewis acids and bases, Brønsted-Lowry acids and bases, ionization, and more are covered by this chemistry handout. It serves as a review of a specific textbook section, but will also serve as a nice review for any general chemistry...

Here is a chemistry worksheet that was designed for a specific textbook section dealing with oxidation-reduction reactions, but it can be used in conjunction with any general chemistry curriculum. To complete the page, learners must...

An interesting set of details about the light spectrum, these slides explain how objects reflect and absorb light to affect how they appear to the human eye. The differences in mixing lights or pigments is explained and some everyday...

These attractive slides explain the basics of the electromagnetic spectrum and then display the emission spectra for a number of elements. argon, helium, hydrogen, xenon, neon and krypton are shown here and two graphs showing log scale...

Wow! Colorful and simple, these 160 slides introduce the various forms of energy, along with a relevant image. Some of the images are animations, which help beginning physical scientists to visualize the flow of electrons or energy! This...

Fascinating aspects of electromagnetic radiation and its use in obtaining and transferring information are described here. Learners will find the connections to current technology interesting. Although the slides are text-heavy, they do...

Slides and slides of emission spectra bring this topic to light for your physics class! Exited electrons returning to lower energy levels is offered as the cause of emission spectra. In summary, viewers learn that we can determine the...

Mostly what you will find here is a history of quantum mechanics. Influential scientists are introduced (along with some of their recorded quotes), the progression of atomic models is reviewed, and finally experssions and equations are...

Using chlorine as the model to demonstrate the structures and representations, this PowerPoint clearly labels and details the main atomic structures and reasons for bonding. The electrons in the outer shell are diagramed and then the...

The principles of pollution control on a molecular level are summarised here. The reasoning and study behind the principles are described, and your class will undestand how some techniques are developed to be more efficient.

After giving the definitions of the different compound terms and formulas, equations are provided to teach your chemists to calculate different values. Relative formula mass, atomic mass, and empirical mass are shown and explained with...

As the title implies, here is a collection of typical photoelectric effect problems that physics learners need to be able to solve. They determine the amount of energy of a photon, the photons produced per second, the frequency required...

This concise collection of images speaks volumes about the trends in the periodic table of elements. Different versions of the periodic table are displayed demonstrating different trends. Teachers' notes are included to assist your...
