    • 2.1: Dalton’s atomic theory
      Dalton's atomic theory describing an atom of an element is presented.
    • 2.2: Subatomic particles and a modern view of an atom
      Subatomic particles, i.e., electrons, protons, and neutrons, along with the modern view of atom, i.e., who the subatomic particles are arranged in an atom are described.
    • 2.3: Atoms of elements
      Symbols of elements and the terms atomic number, mass number, atomic mass, and isotopes are introduced.
    • 2.4: The periodic table
      The periodic table, i.e., the arrangement of elements in columns and rows based on their atomic number is described. The classification of elements into metals, metalloids, and nonmetals, the classification based on their physical states are also described.
    • 2.5: Electrons in atoms
      Quantization of electron energies, the arrangement of electrons in an atom, and the rules for determining the electron configuration of 1st twenty elements are described.
    • 2.6: The periodic trends in properties of the elements
      Periodic trends in atomic size, ionization energy, and electronegativity are described. The trend of valence electrons that determine the chemical characteristics of an element and their representation in Lewis dot symbols is also presented.
