The scientific method and conversions are studied in this chapter: scientific notation, metric system of units, difference between intensive/extensive and between accuracy/precision, significant figures, calculated numerical results and dimensional analysis.
Atoms and molecules are studied in this chapter: elements in chemistry, states of matter, atomic theory, difference between atoms, isotopes and ions, chemical nomenclature of compounds.
The periodic table and chemical periodicity are studied in this chapter: law of constant composition, molecular and molar masses, difference between empirical and molecular formula, chemical reactions and how to balance a chemical equation, groups and periods in the periodic table and their properties.
Early quantum theory is studied in this chapter: ionization energies, wave model of light, photons and photoelectric effect, wave-particle duality, quantization of the energy of the electron in a hydrogen atom and electronic transitions.
Quantum theory and atomic structure are studied in this chapter: Heisenberg uncertainty principle, Schrödinger equation, quantum numbers, electron spin, atomic energy states and electron configuration, Pauli exclusion principle, Hund’s rule, excited states, periodicity of atomic radii, ionization energy and electron affinity.
Ionic bonds and compounds are studied in this chapter: the difference between ionic and covalent bonds, the ionic charges and chemical formulas, the transition metal ions, the sizes of ions, the ionic bond energies.
Covalent bonds and Lewis formulas are studied in this chapter: electron sharing, Lewis structures, formal charges, resonance hybrids, free radicals, expanded valence shells, electronegativity, polar bonds and dipole moments.
Molecular geometries are studied in this chapter: molecular shape, VSEPR theory and prediction of molecular geometry, lone pair effects, the relation between structure and dipole moment, optical isomers and chirality.
The covalent bonding is studied in this chapter: valence bond theory, molecular orbital theory, multiple bonds, hybridization and hybrid orbitals, molecular orbital diagrams.
