Chemical_bonds_and_reactions

Find out how atoms interact with each other to form bonds! We'll look at the different types of strong bonds, including nonpolar covalent, polar covalent, and ionic bonds, as well as weak bonds such as hydrogen bonds and London dispersion forces.

Electron_shells_and_orbitals

Learn how electrons are organized in atoms! We will cover the Bohr model, electron shells, and orbitals, as well as periodic table trends in electron configurations and reactivity.

Chemistry_of_life_skill_checks

Check your understanding of the basic chemistry that makes life possible!

Elements_and_atoms

Learn what matter is made of! We'll cover elements, atoms, and subatomic particles (protons, neutrons, and electrons). We'll also check out isotopes, radioactivity, and carbon dating.
