Chemistry Lesson Topics

  1. What is Science?
    In order to study chemistry you must first understand what science is and is not. Science is unlike any other discipline ...
  2. Experimental Process
    The most important part of good science is designing the experiment. You must design your experiment with as few variables as possible and have control of everything else.
  3. Matter
    Since the basic sciences all deal with matter, it is necessary that you know a little bit about matter. The entire universe is made up two things ...
  4. Properties of Matter
    Since the basic sciences all deal with matter, it is necessary that you know a little bit about matter.
  5. Metric System
    Metric System - It is imperitive that you know the metric system if you plan to be successful in any science field. The metric system is the science standard for measurement.
  6. Scientific Notation
    Scientific Notation - Scientific notation provides a easy method for writing very small and very large numbers while maintaining accuracy and precision with sig figs.
  7. Significant Figures
    Significant Figures - Scientists collect large amounts of data and most of this data comes from measurements and calculations. Therefore, a system is needed to show the precision of their data and calculations.
  8. Unit Analysis
    Unit Analysis - In chemistry, it is not uncommon to change from one system of measurement to another. The best method to accomplish this change is unit analysis.
  9. Atomic Structure - The Development of the Atomic Model
    The purpose of this website is to familiarize the chemistry student with the history, development and structure of the quantum mechanical model of the atom.
  10. Atomic Particles
    Subatomic particles - the electron, the proton and the neutron reveal the structure and reactivity of matter
  11. The Atomic Number and Henry Moseley
    The new concept of the atomic number brought even more power to the periodic table. Instead of the elements being arranged by ...
  12. Quantum Theory
  13. Quantum Numbers
    Quantum numbers describe the orbital occupied by an electron in terms of distance from the nucleus ...
  14. Atomic Orbital Shapes
    Within an energy level there are four possible sublevels each with a characteristic shape. The value of the sublevels can be ...
  15. Electron Configurations or Arrangements
    The electron configurations are the arrangements of the electrons in an atom. It is how the electrons are arranged that helps us understand ...
  16. Valence Electrons
    Valence electrons are the electrons in the highest energy level of an atom and involed in the ...
  17. Lewis Dot Diagrams
    Lewis Dot Diagrams are a symbolic representation of the valence electron arrangement in an atom. Also known as Lewis Dot Symbols.
  18. Lewis Structures
    Lewis Structures are symbolic representations of molecules and polyatomic ions.
  19. The Periodic Table
    The periodic table of the elements is one of the most powerful tools in science; a single document that consolidates our knowledge of chemistry.
  20. Periodic Trends
    There are four trends found in the periodic table: electronegativity, atomic radii, electron affinity and ...
  21. Chemical Bonds
    Chemical bonds are electrostatic attractions between two or more atoms strong enough to allow the atoms to act as a unit.
  22. Covalent Compounds
    Covalent compounds consist mostly of covalent bonds between the atoms and are represented by molecules.
  23. Ionic Compounds
    Ionic compounds consist mostly of ionic bonds between the atoms and are represented by formula units.
  24. Naming Compounds
    Naming compounds can be a daunting task if you don't know the right way to go about it. You can't memorize chemical names. You need a system.
  25. Avogadro's Number - Atomic Mass - The Mole
    Avogadro's number is the number of particles in exactly 12.00 grams of carbon. One mole equals 6.022 x 10^23.
