BASICS 1: IntroductionWhat exactly is a molecule?A molecule is made up of atoms What is an atom? Does an atom have components? More about atom components Charge neutrality: a basic principle How big is an atom? What does one look like? To think about: Can you distinguish between an atom and a molecule? Can you do it coherently, supporting your ideas with chemical examples? Can you distinguish between an ionic and neutral atom?Can you explain how an atom is constructed?The periodic table is a list of the different kinds of atoms The atomic number is how nature knows the identity of an atom A substance made up of one kind of atom is called an element Gross anatomy of the periodic table A substance made up of more than one kind of atom is called a compound Dumb question: What's a substance? To think about: Can you relate the types of elements (metals, nonmetals, and metalloids) to their location in the periodic table?Can you distinguish between elements, compounds, atoms, molecules, mixtures and pure substances?Chemical bonds hold atoms together in molecules Models help us visualize molecules. Different kinds of models emphasize different attributes of molecules. What is a chemical bond?Preliminary rules for chemical bonds The emphasis is on PRELIMINARY To think about: Can you distinguish between an ionic and covalent bond?Can you make accurate estimations of the structure of simple compounds based on the number of bonds that the atoms in that compound characteristically form?Returning 360 degrees we ask our original question againWhat is a molecule? Does a molecule have components? How big is a molecule? What does one look like? To think about: Can you distinguish between an atom and a molecule? Can you do it coherently, supporting your ideas with chemical examples? Can you distinguish between an ionic and neutral atom?Do you have a mental picture of what a molecule looks like?BASICS 2: Big MoleculesIs it really this simple?No Macromolecular Substances Polymers A protein is a kind of polymer Network solids Ionic compounds What's an ion? Metallic substances A name to sum this upTo think about: Do you understand the difference between a molecule and a macromolecule?Can you differentiate between the three major classes of macromolecular compounds?Do you understand the idea of an allotropeBASICS 3: Bonding & NamingBonding and NamingThere are three different kinds of chemical bond ionic So, what's an ion? An ion can be a charged atom This is called a monatomic ion An ion can be a charged collection of atoms This is called a polyatomic ion Polyatomic ions worth knowing covalent Chemists use shorthand, called molecular formulas, for writing down molecules Molecules have fixed formulas These formulas arise from our PRELIMINARY rules Molecular formulas metallic Some notes at the end (or is it the middle?)To think about: Can you connect the appearance of a molecular model with a chemical formula?Can you figure out the molecular formulas for simple compounds containing hydrogen, oxygen, sulfur, nitrogen and the halogens?Naming a compound Is it ionic or covalent? Ionic compounds Covalent compounds To think about: Can you explain the differences between the three major kinds of bonding?Can you predict, using the periodic table, whether a compound will contain ionic bonds or covalent bonds?Can you translate from formula to name and from name to formula?Do you know the simple trivial names of common compounds?BASICS 4: Chemical ReactionsChemical reactionsWhat is a chemical reaction? What isn't a chemical reaction The chemical equation describes chemical reactions Details of the chemical equation Quantitative meaning of the chemical reaction The mole Atomic weights Molecular weights Formula weights Some simple calculations How much reactant gives how much product To think about: Can you explain the difference between a chemical and a physical process?Can you interpret all the symbols used in a chemical equation?Can you calculate formula weights?Can you calculate the number of moles of a compound is in a sample if you know the mass of the sample and vice-versa ?Can you use chemical equations to predict the amount of product you can expect from a given amount of reactant?BASICS 5: Math ReviewA Little MathRatios Decimal equivalents Algebra: The one and only rule Important variables How to manipulate them Verify your answer using dimensional analysis Units of measure Greek prefixes Dimensional analysis and unit conversion To think about: Can you do simple algebraic manipulations, particularly in definitions involving three variables?Can you use dimensional analysis to check your algebra?Can you convert between units of measure using dimensional analysis?BASICS 6: SolutionsSolutionsWhat is a solution Solution math Molarity Solutions math Dilution per cent by mass To think about: Can you calculate V, M, and n using the definition of molarity?Can you figure out how to dilute a solution in order to obtain a solution of a particular target
