All matter in the observable universe-from a single blade of grass to a planet in a faraway galaxy-is made up of atoms, molecules, and compounds. This program introduces these minuscule building blocks in five sections: The Nucleus (protons and neutrons, energy shells, binding energy, fission and fusion); The Electrons (quantum numbers, spdf orbitals); The Elements (periodic table, valence electrons, ions and ionization energy, electronegativity, covalent and ionic bonds); The Energy of Atoms (exothermic and endothermic reactions, spontaneous reactions, Gibbs free energy, activation energy, catalysts); and Common Compounds (properties of sodium chloride and water, polarity).
