Grading- Quizzes: 10 %. Distributed periodically, graded
generously.
- Homeworks: 15%. Distributed weekly.
- 3 Midterms: 50% total
- 1 Final: 25%
The following grading scheme will be used:
2.0 for ≥50%, 1.5 for ≥40%, 1.0 for ≥30%, 0.5 for ≥20%0 for <20%
Note that these percentages represent the maximum needed for a given grade and I am generous when it comes time to assigning a final grade.
4.0 for ≥90%, 3.5 for ≥80%, 3.0 for ≥70%, 2.5 for ≥60%,
Format of the ClassHomework
There will be homework problems assigned weekly to help reinforce information presented in the lectures and the textbook. Homeworks need to be turned in by the beginning of the class indicated on the header of the homework in order for full credits to be given. Late homeworks will be graded with a 50% penalty. All completed homework need to be turned in to pass the class, no matter the grade.
Quizzes Quizzes will be distributed periodically – these quizzes are intended to be short (~5 to 10 minutes), and will be designed to help you stay on track with the new material covered in class. Most of the time, these quizzes will be given at the end of one class and due at the beginning of the other, but in-class quizzes might also be distributed. In general, quizzes will be graded very generously – the idea is to encourage you to at least give it a try; nevertheless, missed or late quizzes will not be graded.
MidtermsThere will be three midterm exams; each are cumulative, but with a large emphasis on the more recent materials covered before each exam. The midterms will be given outside regular class time to allow for extended exam time. No make-up midterm exams will be given. In the event of illness or other extenuating circumstance, you must notify the instructors prior to the examination. Appropriate documentation will be required, and you will be assigned a score based upon the weighted average score of your other examinations and of your final exam. Only one mid-term exam may be missed—if a second exam is missed the grade on that exam will be zero.
On the day of each exam, the class will be replaced by a recitation to review the materials of each exam.
Format of the Class

What is Inorganic Chemistry?
Inorganic chemistry is the study of the synthesis and behavior of inorganic and organometallic compounds. It has applications in every aspect of the chemical industry–including catalysis, materials science, pigments, surfactants, coatings, medicine, fuel, and agriculture. Inorganic chemists are employed in fields as diverse as the mining and microchip industries, environmental science, and education. Their work is based on understanding the behavior and the analogues for inorganic elements, and how these materials can be modified, separated or used–often in product applications. [...] Inorganic chemists compare their jobs to those of materials scientists and physicists. All three fields explore the relationship between physical properties and functions, but inorganic chemistry is the most keenly focused on these properties at the molecular level.

Characteristics of Inorganic Compounds
• d and f orbitals are populated, or easily accessible
• very weak to very strong bonds
• wide variety of geometries
• can have unpaired electrons (magnetism)
• Low-energy electron excitations
• Many stable oxidation states

Niels Bohr (1885 - 1962)
The atom is: 1) Negatively charged particles
(electrons) orbiting around 2) a positively charged and heavy
nucleus 3) on circular orbits of very precise
radii.The Rutherford-Bohr Atom:
An electron can change its orbit by absorbing or releasing energy under
the form of light
Problems with the Bohr Model:
Why is the electron not falling onto the nucleus? What makes it “stay” on precise orbits?
The Bohr model only works for atoms with one electron, that is, it only works in practice for hydrogen…
The Bohr model says nothing about molecules, which means that it is not very useful for chemists.
