Videos on chemistry (roughly covering a first-year high school or college course). <\/p>\n
Atomic structure, atomic numbers, atomic mass, moles, ions (eventually), compounds (eventually) <\/p>\n
We are now going to delve into the heart of chemistry. We learn ways of representing chemical molecules and how molecules react. To do this, we'll even think about \"how many\" of a molecule we have using a quantity called a \"mole\". <\/p>\n
Bohr model, absorption, emission spectrum, quantum numbers, electron configurations <\/p>\n
Classification of elements, atomic radii, ionic radii, ionization energy, electron affinity <\/p>\n
Ionic bonds, metallic bonds, covalent bonds, electronegativity, VSEPR, hybridization <\/p>\n
Gas laws (eventually), ideal gas equation, Dalton's law (eventually), kinetic molecular theory (eventually) <\/p>\n
<\/p>\n
