Chemistry 1B with Will

Will’s Chemistry 1B – Section 0002 with Dr. Patino

About Me

Hello!  My name is Will.  I was born in Brazil, but lived most of my life in Kansas.  I have a BS in Arabic and Education as well as AA’s in: Portuguese, French, and Intel.  I was in the Air Force for 7 years as a Crypto-Linguist and am now pursuing my degree in Biotechnology.

Why Supplemental Instruction?

I was skeptical at first, but after attending my first SI session last spring, I was immediately impressed!  It’s such a unique approach to, well, becoming a pro at college.  Though it may be hard at first to see how going to a session where the SI leader can’t directly answer your questions is helpful, the statistics don’t lie.  Students who regularly attend SI (average of 2 times per week) achieve an average of a whole letter grade higher than those who don’t.  If that’s not enough, it’s important to remember how awesome it can be to put into practice the things learned in lecture.  The advantages go beyond the letter grades and into the realm of subject mastery.

What should you do?

First and foremost, attend!  At worst, it won’t hurt.  At best, you’ll love it, exceed the statistics and ace your class, and have a better understanding of Chemistry.  Also helps to bring your materials: book notes, lecture notes, past quizzes/exams, and best of all…QUESTIONS!  You’ll find that it’s a relatively informal approach to group study and that you’ll have a chance to ask the questions you’re really having trouble understanding.  Be prepared to be involved.  As one with an education degree can attest to, learning by doing (aka, asking questions, participating in discussion, and possibly best of all, helping someone else understand a concept) has been proven many times over to indicate subject mastery (aka getting better grades, aka winning, aka being a BAWS, aka being confident that you can and will succeed in both college and beyond).
Side Note: That was a lot of akas!

My SI times/locations will be posted here the entire semester for your convenience.  Additionally, I will be posting some helpful materials that either have come directly from Dr. Patino or reviews for exams, or additional information about topics covered in lecture…you get the picture.

Below are my SI times and locations!  Hope to see you!



Note: This is not a comprehensive review, these are just some of the things I highlighted in my notes from lecture as well as some of the things we covered in our SI sessions.  Remember that all of chapter 7 is fair game as well as whatever we covered in chapter 8.  It would be wise to compare this to your notes and the power point slides/book to ensure maximum success.

Waves – Know the following terms, how to identify them if given a picture of a wave, and how they are used in equations.
* Amplitude
* Wavelength
* Frequency

Be familiar with units to all equations and constants, it sounds like a lot of work, but it pays off in ensuring you get the right answers and understand why.

* Speed of Light: c = 2.998 x10^8 m/s
— c(m/s) = λ(m) * ν(1/s)

Names – Be familiar with the names, usually last name is enough to identify on a test question, but can’t hurt to know the whole name.  Also know why we should know these names.  Also be familiar with the terms behind what they did (ex: photoelectric effect).  The dates aren’t necessarily important except it’s good to know how they are interconnected (ex: quantizing energy led to others).
* Max Planck: quantized energy E = hν (yr. 1900)
* Albert Einstein: photoelectric effect (yr. 1905)
* Niels Bohr: 2D version of atom
* Balmer (yr. 1885), then Bohr (yr. 1913)
* Louis de Broglie: wavelike properties of matter (yr. 1915)
* Werner Heisenberg: Uncertainty Principle (yr. 1923)
* Erwin Schrodinger: Schrodinger Equation (yr. 1926)

Equations – Most of these (if not all) should be given to you on the exam from what Dr. Patino said in class.  However, it’s good to know how they work and which ones apply where.  We covered in SI how important it is to use the correct equation, when to go further on an exam problem and when to stop.  We also covered how to check to make sure we stopped where we need to (units match, etc).

* Planck’s Constant (h): h = 6.626 x 10^-34 J*s/photon
* Planck’s Equation: E = h*ν -> therefore -> E = h * c/λ
* Rydberg Constant (R): R = 1.097 x 10^7 m^-1
* Rydberg Equation: 1/λ = R(1/n^2 – 1/n^2) [denomiators are: n final and n initial]
* Balmer Series Constant (RH): RH = 2.18 x 10 ^-18 J/atom
* Balmer Series Constant: ΔE = RH(1/n^2 – 1/n^2)
* Heisenberg Uncertainty: (Δx)(Δp) ≥ h/4π  [p = momentum = mass(m) * velocity(v)]

Know how to manipulate these equations, combine them, and discern which ones you need for what is given to you.  Also remember that things learned in CHM 1A may be useful (Avogadro’s number and unit conversions).

Review charts and diagrams given in lecture (Energy levels, electromagnetic spectrum, etc).

Electron Configuration
We covered the n(shell), l(subshell/angular momentum), ml(magnetic quatum number), ms(magnetic spin) chart in the last couple SI sessions as well as how to do electron configuration.  Be familiar with what those letters mean, what they stand for, and how they relate to what an electron looks like and it’s configuration.  (sphere, peanut, donut, flower).
(ex: If given an element, you should know how to write up the element’s configuration.  If given a configuration, you should be able to derive the element.)

Note: We covered how to see it better on the periodic table in SI.  Good idea to keep to look over it and when given a test, as long as you can write on the test, you could label things you may want to reference later.

Be familiar with Hund’s rule, Pauli Exclusion Principle, and the Aufbau Principle.  Remember Dr. Patinos’ Mnemonic device for remembering the order in electron configuration.

Hopefully you all get a chance to review this as well as all your notes and power point slides.  The practice questions at the back of the book and reviewing previous quizzes are also great tools at your disposal.

Monday, I may try to do a Jeopardy review game, so come ready to win!  There may be prizes!  Good luck, you’ve got this!
