McMaster Students Offering Support – Fall 2011 CHEM 1A03 Review Package
What is Students Offering Support?
Students Offering Support is a national network of student volunteers working together to
raise funds to raise the quality of education and life for those in developing nations
through raising marks of our fellow University students.
This is accomplished through our Exam-AID initiative where student volunteers run group
review sessions prior to a midterm or final exam for a $20 donation.
All of the money raised through SOS Exam-AIDs is funnelled directly into sustainable
educational projects in developing nations. Not only does SOS fund these projects, but SOS
volunteers help to build the projects on annual volunteer trips coordinated by each
University chapter.
Tips for Test Success
Focus on specific problem types given in the study package. As the formats of previous and
current tests are quite similar, types of questions given in the package will be asked on the
test.
Know the most common formulas and pay attention to how to use them. Even if you might
have a list of formulas, you need to know the applications. Especially, distinguish between
formulas for standard and non-standard conditions.
Check units and measurements for each variable. Getting a wrong unit at the end indicates
that something might be missed in the solution. Also, remember which units are used in
formulas in order to convert them if needed.
Practice a sample quiz as it is a real test and do not look at the answer before you solve the
whole problem. Having an answer in mind before doing a problem can lead to the
adjustment of the answer without having the right solution.
Get adequate sleep the night before your test. Sleeping at night helps consolidate what you
learned during the day into memory so that it is better remembered in future. Not only
does staying up late the night before a test destroy your concentration during the test the
next day, but your brain has not effectively learned the material.

Chapter 8: Electrons in Atoms
Frequency/wavelength/velocity
• v = velocity
• c = speed of light
• λ = wavelength
• f = frequency
• v = fλ or v = c/λ
ER spectrum
• Electromagnetic waves can have an infinite range of frequencies (or wavelengths)
• Some frequencies (wavelengths) are visible to the unaided human eye, which interprets
different frequencies as different colours
• Most of the frequencies are not visible to the human eye
Emission Spectra
• Every element has a unique spectrum
• Each wavelength in a spectrum is called a spectral line
• When a sample is excited, only certain wavelengths of light are observed
• The reason for distinct spectra = energy is quantized (discontinuous)
Planck’s equation photoelectric effect
• E = hf, where h = Planck’s constant
• The emission of electrons from a material surface when light strikes its surface is called the
photoelectric effect
• The electromagnetic wave’s energy is used to ionize atoms on the surface, extracting
electrons
• The electrons emitted from the metal surface due to incident light on its surface;
photoelectrons
