 (1.4) Units – SI base units
 (1.4) Prefixes – Be able to convert from one prefix within the SI system to
another (Know: Kilo, Centi, Milli, Micro)
 (1.4) Significant Figures – How many in a given number? – Scientific notation!
 (1.4) Temperature scales – Be able to convert between Fahrenheit, Celsius
and Kelvin
 (1.4) Units – You will be provided with conversion factors between SI units

 (1.2, 1.4) Derived Units (ex. density, volume)
 (1.5) Problem Solving – Use ratios to convert units and use them in problems
(like the examples in class, homework and on the quiz – Nuts and Bolts..)
Chapter Two – Atoms and Molecules
 (2.2) Structure of the atom – protons, neutrons, electrons – mass and charge of
each
 (2.2) Atomic Symbols – know the names and Atomic Symbols of the
following elements: The First 20 elements (Through Calcium), and
Fe (Iron), Co (Cobalt), Ni (Nickel), Cu (Copper), Zn (Zinc), Ag (Silver),
Sn (Tin), Au (Gold), Hg (Mercury), Pb (Lead), Ba (Barium)
 (2.2) Atomic Number vs. Mass number
 (2.2) Isotopes – what are they? How are they formed?
 (2.2) Nuclide symbols – What information is conveyed and where is it?
 (2.2) Atomic Weight, Atomic masses, and atomic mass units (amu)
 (2.3) Ions, cations, anions, ionic compounds, Ionic formulas, monatomic ions
vs. polyatomic ions
 (2.2) Calculate atomic weight from isotopic fractional abundances or calculate
fractional abundances given atomic weight – Like examples in class or on
the homework (think Nuts and Bolts lab)
 (2.4) Chemical Formulas, Molecular Formulas, Ionic Formulas
 (2.5) Periodic Table – Group vs. Period, Metals vs. Non-metals, Metalloids, Main
group elements vs. transition metals
 (2.5) Alkali Metals, Alkaline Earth Metals, Halogens, Noble Gases –
Examples of each
 (2.6) Organic Chemistry vs. Inorganic Chemistry – What are they? What are
functional groups? What are hydrocarbons?
Chapter Two – Chemical Nomenclature
 (2.7) Naming ionic compounds (Metal + non-metal) ex. NaCl = Sodium chloride
o Determine charges on cations and anions
o Be able to figure out transition metal charges from name or structure –
You DO NOT have to memorize the multiple charges on transition
metals and You DO NOT have to learn –ous and –ic naming rules
o Polyatomic ions – you will be provided with a table on the reference
sheet containing the formulas of common polyatomic ions
o Be able to convert from –ate to –ite (lose 1 oxygen), to hypo- -ite (lose 2
oxygens) and from –ate to per-ate (add 1 oxygen) ex: Chlorate,
chlorite, hypochlorite, perchlorate (EXTRA CREDIT ONLY!!!)
 (2.7) Naming covalent compounds (Non-metal + non-metal) ex. CO2 = carbon
dioxide (Know the prefixes up to 8)
Chapter Six – The Periodic Table and Atomic Structure
 [6.2] Wave Theory of Light – Know the definitions of frequency, wavelength,
amplitude of a wave
 [6.2] Electromagnetic Spectrum – Understand the relationships between
frequency and wavelength. You need to know the formula c=λν. You
also need to know how to convert meters to nanometers (nm). I will
provide the value of c (Speed of light in a vacuum).
Rules for Exam
1. You will need your calculators.
2. You will be provided with a reference sheet and periodic table identical to those
on the website
3. NO OTHER outside information may be used.
Exam will consist of a combination of multiple choice, fill in the blank, and
calculation problems.
Advice
Study the suggested problems and answers on the website as well
as the quizzes – many problems/questions will be similar those.
Study your lecture notes and textbook sections provided above.
Watch the time on the exam – do not spend too much time on a
problem you are unsure of!!!! I provide point values for each
problem and you are limited to 50 minutes to complete the
exam!
