Law Of Conservation Of Mass

When two atoms with unequal electronegativities form a covalent bond, the electrons contributed to the resulting molecule are shared unequally between them. This creates an uneven distribution of partial charges across the molecule, which is defined as molecular polarity. This simulation shows this concept in action. You will learn about dipoles, partial charges, electrostatic potential, electron density through experimenting with different variables and seeing their effects on a molecule.

Concentration is a familiar concept to most of us in our daily lives. We all know that adding too much coffee powder to our coffee can result in a too-strong beverage, while too little may result in a diluted, unimpressive morning coffee. Play with this simulation to visualize the relationship between the solute, solvent and their respective volumes!

We hear about the concept of 'radiation' all the time, especially in medical terminology. Radiation, however, occurs when an unstable, high-energy nucleus of an element releases some of that energy to get to a more stable state (similar to when we consume way too much candy and need to work off all of that energy!). Alpha decay is one of the ways this excess energy is expelled!

Chemistry

Chemistry is the branch of science that deals with the study of matter! Did you know that chemistry is also called “the central science,” because of its role in bridging physics with other natural sciences? Let's dive into learning more on the composition and the physical and chemical properties of various forms of matter!  

Explore modern atomic theory by performing the experiments that established it, build your own atom in 3D, and use study guides and gamified challenges to become an expert on atomic structure!
