Chemistry

Did you know that everything is made out of chemicals? Chemistry is the study of matter: its composition, properties, and reactivity. This material roughly covers a first-year high school or college course, and a good understanding of algebra is helpful.

Dot structures

We can’t always see molecules, but we can always simplify and draw depictions of them with pen and paper. It is the language of chemistry that we want you to get acquainted with. You will learn to draw Lewis dot structures and resonance structures, assign formal charges, and analyze the geometry of molecules and ions using VSEPR theory.
