Bohr Model / Quantum Mechanics Test

Unfortunately, I will not have time to make up some practice questions for Monday's test over the material in Chapter 10. I have a plumbing emergency at my house and I do not have the time to spend on it. I will map out some things that you should know.

• Know about the "Light / Quantum Mechanics" packet. Know how to use all equations in the packet. All equations and constants will be supplied.
• Know the order of filling orbitals by using a periodic table. I will be supplying you with a periodic table for the test.
• Know the concept of penetration by an electron to lower principle energy levels and how this concept dictates the order on how the sub-levels and orbitals of different energy levels are filled.
• Know the shape of an "s" orbital (sphere) and a "p" orbital (dumb bell)
• Know the sub-levels that are in each principle energy level. 1st - s only; 2nd - s and p; 3rd - s, p, and d; 4th (and on) s, p, d, and f.
• Know how many orbitals are in each sub-level. You should be able to calculate how many electrons could be held in a particular principle energy. For example: How many electrons could be in the 4th principle energy level? The 4th principle energy level is the first time all of the sub-levels are present. Therefore; 1 orbital for the s, 3 orbitals for the p, 5 orbitals for the d, and 7 orbitals for the f will be a total of 16 orbitals. Each orbital can hold 2 electrons for a total of 32 electrons in the 4th principle energy level.
• Know how to write orbital diagrams, complete electron configurations, and noble gas electron configurations.
• Know the abnormalities for the electron configurations of chromium and copper.
• Know the difference between a ground state electron configuration and an excited state electron configuration.
• Know para-magnetism and di-magnetism based upon unpaired and paired electrons in an orbital.

The test is written and multiple choice. There are five written questions and 26 multiple choice questions.
