Chemistry is the study of the composition, structure, and properties of matter, as well as the changes it undergoes during chemical reactions. Chemistry focuses on the interactions between different types of matter, particularly reactions that involve electrons.

Topics: Periodic Table, Balancing Chemical Equations, Writing Balanced Equations, Stoichiometry, School Chemistry, Chemistry & Physics Experiments, High School Chemistry, General Chemistry I, General Chemistry II and Organic Chemistry.

Periodic Table

We will start with some lessons on atoms and the elements in the Periodic Table.
