The smallest known building blocks of our world are sub-atomic particles. This section provides an introductory course about the atomic nucleus and decay, electronic structure and models, the periodic table, and stoichiometry. We cover the Bohr model and discuss various trends in the periodic table which will build your foundation for dealing with more advanced chemistry topics and passages on the MCAT.
