Chemistry 101 - Introduction and Index of Topics

Chemistry 101 - Introduction and Index of Topics Welcome to the world of Chemistry 101! Chemistry is the study of matter. Like physicists, chemists study the fundamental properties of matter and they also explore the interactions between matter and energy. Chemistry is a science, but it is also used in human communication and interaction, cooking, medicine, engineering, and a host of other disciplines. Although people use chemistry every day with no apparent problem, if the time comes to take a course in chemistry in high school or college, many students are filled with dread. Dont be! Chemistry is manageable and even fun. Ive compiled some study tips and resources to make your encounter with chemistry easier. Not sure where to start? Try Chemistry Basics. Periodic Table of the Elements You need a trusty periodic table for practically all aspects of chemistry! There are links to characteristics of elements groups, too. Periodic TablePrintable Periodic TablesGroups of Elements Periodic Table Helpful Resources Use these resources to look up unfamiliar terms, identify chemical structures, and recognize the elements. Worked Chemistry ProblemsChemistry GlossaryChemical Structures ArchiveInorganic ChemicalsElement PhotographsFamous ChemistsScience Lab Safety Signs Introduction to Chemistry 101 Learn about what chemistry is and how the science of chemistry is studied. What Is Chemistry?What Is a Chemical?What Is the Scientific Method? Math Basics Math is used in all the sciences, including chemistry. To learn chemistry, you need to understand algebra, geometry, and some trig, as well as be able to work in scientific notation and perform unit conversions. Accuracy Precision ReviewSignificant FiguresScientific NotationPhysical ConstantsMetric Base UnitsTable of Derived Metric UnitsMetric Unit PrefixesUnit CancellingTemperature ConversionsExperimental Error Calculations Atoms and Molecules Atoms are the basic building blocks of matter. Atoms join together to form compounds and molecules. Learn about the parts of the atom and how atoms form bonds with other atoms. Basic Model of the AtomBohr ModelAtomic Mass Atomic Mass NumberTypes of Chemical BondsIonic vs Covalent BondsRules for Assigning Oxidation NumbersLewis Structures and Electron Dot ModelsIntroduction to Molecular GeometryWhat Is a Mole?More About Molecules MolesLaw of Multiple Proportions Stoichiometry Stoichiometry describes the proportions between atoms in molecules and reactants/products in chemical reactions. Learn about how matter reacts in predictable ways so that you can balance chemical equations. Types of Chemical ReactionsHow to Balance EquationsHow to Balance Redox ReactionsGram to Mole ConversionsLimiting Reactant Theoretical YieldMole Relations in Balanced EquationsMass Relations in Balanced Equations States of Matter The states of matter are defined by the structure of matter as well as whether it has a fixed shape and volume. Learn about the different states and how matter transforms itself from one state to another. States of MatterPhase Diagrams Chemical Reactions Once you have learned about atoms and molecules, youre ready to examine the type of chemical reactions that can occur. Reactions in WaterTypes of Inorganic Chemical Reactions Periodic Trends The properties of the elements exhibit trends based on the structure of their electrons. The trends or periodicity can be used to make predictions about the nature of the elements. Periodic Properties TrendsElement Groups Solutions Its important to understand how substance dissolve and how mixtures behave. Solutions, Suspensions, Colloids, DispersionsCalculating Concentration Gases Gases exhibit special properties based on having no fixed size or shape. Introduction to Ideal GasesIdeal Gas LawBoyles LawCharles LawDaltons Law of Partial Pressures Acids Bases Acids and bases are concerned with the actions of hydrogen ions or protons in aqueous solutions. Acid Base DefinitionsCommon Acids BasesStrength of Acids BasesCalculating pHpH ScaleNegative pHBuffersSalt FormationHenderson-Hasselbalch EquationTitration BasicsTitration Curves Thermochemistry Physical Chemistry Learn about the relationships between matter and energy.

Kinetics Matter is always in motion! Learn about the motion of atoms and molecules, or kinetics. Factors that Affect Reaction RateChemical Reaction Order Atomic Electronic Structure Much of the chemistry that you learn is associated with electronic structure, since electrons can move around much more easily than protons or neutrons.
