Need Help with the CHEMICAL BONDS unit?
|
Check for understanding. The following link will take you to a 12 question quiz that will test your understanding of bond types based on electronegativity value differences. At the conclusion of the quiz you will be given feedback along with an opportunity to review your answers.
|
How to make ionic bonds. A good review of what we have discussed in class. (And yes, she does talk faster than Mrs. Zimny...didn't think that was possible did you?)
|
Lewis Structures with covalent bonds--a good review of single, double, and triple bond formation.
|
A GREAT explanation of resonance structures! Good review!
|
Highly encourage you to watch this video to review VSEPR structures if you are struggling with this concept!
|
VSEPR Practice Problems
|
Assigning Formal Charges
|
Intermolecular Forces Review
|
Hybridization Review--Goes over the how's and why's of basic sp, sp2, and sp3 hybridization that we have covered in class.
|
Need Help with the PERIODIC TRENDS unit?
One throwback from 9th grade is the location of the major groups of the periodic table along with their properties. Check out this powerpoint for a quick review.
|
The above video is a great review of the location of the major groups you need to memorize.
|
The above video is a good review of how to calculate effective nuclear charge.
|
The second half of this video is a good review of the trends that we discussed in class (you will not be held accountable for the metallic character and the electron affinity trends).
|
Need Help with the Electromagnetic Radiation Problem Set?
Calculating wavelength when given frequency.
|
Calculating frequency when given wavelength in nanometers.
|
Calculating frequency from energy.
|
Resources for Quantum Unit
Quantum Mechanics as explained by Brian Greene.
|
"Simple" explanation of the double slit experiment.
|
Writing electron configuration using the spdf blocks of the periodic table.
|
A GOOD review of electron configuration, Aufbau, Pauli, Hund, and orbital notation!
|
Confused with Noble gas configurations?
|
Resources for History of Atomic Theory

Copper Mining In MN?
As you begin your research, your first goal is to learn as much as you can about the proposed mining processes, the benefits and costs to the people and environment of MN. Linked below are some articles to get you started. You should not limit yourself to what you are finding here.
Digging Into the Promise of Copper--MN DNR POLYMET Study--Duluth News Tribune Oct 5, 2013 Flambeau Mine near Ladysmith--DNT Oct 5, 2013 Copper Nickel Mining Divides Ely Residents--MPR May 2013 |
Do you have access to a mobile device? Check out the TrendLine app. Plug in your x,y coordinates and the program will plot a line of best fit and provide an equation on the spot.

Significant Figures Help--are you wanting just a little more practice with significant figures, or could a tutorial help you to solidify them in your brain? Click on the Khan Academy Link for several tutorials and practice questions. If you haven't already signed up for an account with Khan Academy I would highly recommend it as it will help you not only in science this year, but also in your math classes when you get stuck, or when you want to jump ahead and learn something new!
