Textbook
Course Overview:CHEM 2000 is the second half of a full yearcourse in general chemistry. As such, it shouldideally be taken within one year of completingCHEM 1000. The goal of these courses is tointroduce you to university-level chemistryand to give you an appreciation for the diversityof the field. In CHEM 2000, we will continueour study of matter at the atomic level bylearning how atoms bond to makemolecules. We then will learn howthermochemistry and electrochemistrydictate the extent to which reactions arefavoured. Finally, we will introduce some keyconcepts from organic chemistry – functionalgroups, stereochemistry, typical organicreaction types and the role of acid-basechemistry in this discipline.

Grade Composition:
YOU MUST PASS BOTH THE LABORATORY (12.5/25) AND LECTURE (37.5/75)PORTIONS OF THE COURSE SEPARATELY IN ORDER TO PASS THE COURSE.
*Both midterms are on Tuesday evenings. If you have a direct conflict with either time, you must contact the course coordinator (Susan Findlay) at least one week before the test to arrange to write at an alternative time.
The online assignments are a required course component. In order to completethese assignments, you will need to register with the Sapling Learning website (http://saplinglearning.ca), at a cost of $42.
Some General Notes
4
The final exam is cumulative
Practice Problems: The website has a list of recommended practice questions from our text as well as some supplementary practice problems.
Allergy Alert: Latex balloons are used in some demonstrations. If you have any relevantallergy please inform your instructors (lab and lecture).
Calculator Policy: scientific calculators with trigonometric and logarithmic functions as wellas multiple brackets and/or data memories are allowed. Storing/downloading text to yourcalculator is strictly forbidden. Violation of these policies during a test will result inconfiscation, regarded as cheating and will be dealt with accordinlgly. CALCULATORSWITH WIRELESS COMMUNICATION CAPABILITIES ARE STRICTLY FORBIDDEN.
Attendance Policy: Attending the lab is mandatory, and you will be assigned a grade of 0for any lab missed without a valid reason. Please see your lab manual for the correct protocolto make up a lab that was missed due to illness, etc.
Special Needs Students: Please contact the Disabilities Resource Office to arrange for accommodations. Also, feel free to inform your instructor of your special needs in order for you to have a productive learning experience

Cheating and/or plagiarism:
If you are caught cheating on any lab report or quiz, the minimum penalty is a grade of 0 for that report/quiz.
If you are caught cheating on an exam, you will be assigned a grade of F for the course.
In either case, a letter describing your offense will also be placed in your student file.
Repeated offenses trigger progressively more severe forms of discipline. Two letters result in suspension or expulsion from the University.
COPYING HOMEWORK IS CHEATING. If you are caught cheating on yourhomework, the minimum penalty is a grade of 0 for ALL homework in the course. Aletter describing your offense will also be placed in your student file.
STUDENTS WHO CHEAT CHEAT THEIR FELLOW STUDENTS. If you see someone cheating during an exam, inform the instructor in the following way. Write a message on your exam paper indicating what is happening and where. Put your hand up, and the instructor will come over. Point out your note, and the instructor will take it from there. This includes situations where someone may be cheating off you. If you allow someone to look at your work, you are also at fault and you will be disciplined. Recognize that it is often pointless to report cheating after the event.

What have we already learned?

The Atom
i) Plum pudding model
- Discovery of the fundamental particles : p, n & e.
- Rutherford’s famous experiment
What have we already learned?ii) Bohr Model- Nuclear atom- quantized energy and momentum
Energ
y
Frequency
A photon is emitted (absorbed) when
the electron changes from higher
(lower) orbit to lower (higher) orbit
The electron remains in a stable
trajectory around the nucleus
Problem!!
Spectrum of Hydrogen
iii) Quantum mechanical model
- Quantum Numbers
- Electron configurations
- The Periodic Table
n - Principle Quantum Number
l - Angular momentum Quantum Number
Determines which shell the electron is in
and the energy of the electron, E(n)
Subshells exist for each shell differing in the angular momentum value.
m - Magnetic Quantum Number
Related to the orientation in space that of the orbital.
s - Spin Quantum Number
H( Y(n, l, m, s) ) = E(n) Y(n, l, m, s)
