In this lesson, students will learn about the history behind the atomic model and learn how to draw a Bohr model. To draw the models, cards are provided with examples for students to draw. Students can use the PhET Simulation: Build an Atom to check their answers.
How did scientists figure out the structure of atoms without looking at them? Try out different models by shooting light at the atom. Check how the prediction of the model matches the experimental results.
Small molecules are chemicals that can interact with proteins to affect their functions. Learn about the structure and biological functions of various small molecules like sugar and caffeine. Also featured on the HHMI DVD, Scanning Life's Matrix: Genes, Proteins, and Small Molecules. Available free from HHMI.
Start a chain reaction, or introduce non-radioactive isotopes to prevent one. Control energy production in a nuclear reactor! (Previously part of the Nuclear Physics simulation - now there are separate Alpha Decay and Nuclear Fission sims.)

Ancient alchemists attempted but failed to turn different substances into gold. It turns out that the only way to turn one element into another element is using nuclear chemistry! Nuclear reactions change the composition of an atom's nucleus, and this process is useful for many applications.
In this activity, learners explore the question "What is paper?" Learners discover the processes and materials required to make paper while experimenting with different recycled fibers and tools.
Learn how the periodic table organizes the known elements of our world. Check out our videos and exercises on atomic structure and properties and periodic trends.
This course is an introduction to quantum mechanics for use by chemists. Topics include particles and waves, wave mechanics, semi-classical quantum mechanics, matrix mechanics, perturbation theory, molecular orbital theory, molecular structure, molecular spectroscopy, and photochemistry. Emphasis is on creating and building confidence in the use of intuitive pictures.
This course presents an introduction to quantum mechanics. It begins with an examination of the historical development of quantum theory, properties of particles and waves, wave mechanics and applications to simple systems — the particle in a box, the harmonic oscillator, the rigid rotor and the hydrogen atom. The lectures continue with a discussion of atomic structure and the Periodic Table. The final lectures cover applications to chemical bonding including valence bond and molecular orbital theory, molecular structure, spectroscopy.

The material for 5.61 has evolved over a period of many years, and, accordingly, several faculty members have contributed to the development of the course contents. The original version of the lecture notes that are available on OCW was prepared in the early 1990's by Prof. Sylvia T. Ceyer. These were revised and transcribed to electronic form primarily by Prof. Keith A. Nelson. The current version includes additional contributions by Professors Moungi G. Bawendi, Robert W. Field, Robert G. Griffin, Robert J. Silbey and John S. Waugh, all of whom have taught the course in the recent past.
This course provides an introduction to the chemistry of biological, inorganic, and organic molecules. The emphasis is on basic principles of atomic and molecular electronic structure, thermodynamics, acid-base and redox equilibria, chemical kinetics, and catalysis. One year of high school chemistry is the expected background for this freshman-level course.
The aims include developing a unified and intuitive view of how electronic structure controls the three-dimensional shape of molecules, the physical and chemical properties of molecules in gases, liquids and solids, and ultimately the assembly of macromolecules as in polymers and DNA. Relationships between chemistry and other fundamental sciences such as biology and physics are emphasized, as are the relationships between the science of chemistry to its applications in environmental science, atmospheric chemistry and electronic devices.

Professor Drennan would like to acknowledge the contributions of MIT Lecturer Dr. Elizabeth Vogel Taylor, Professor Sylvia Ceyer, and Professor Robert Silbey to the development of this course and its materials.
5.112 is an introductory chemistry course for students with an unusually strong background in chemistry. Knowledge of calculus equivalent to MIT course 18.01 is recommended. Emphasis is on basic principles of atomic and molecular electronic structure, thermodynamics, acid-base and redox equilibria, chemical kinetics, and catalysis. The course also covers applications of basic principles to problems in metal coordination chemistry, organic chemistry, and biological chemistry.

In an effort to illuminate connections between chemistry and biology, a list of the biology-, medicine-, and MIT research-related examples used in 5.111 is provided in Biology-Related Examples.

Development and implementation of the biology-related materials in this course were funded through an HHMI Professors grant to Prof. Catherine L. Drennan. Videos and captioning were made possible and supported by the MIT Class of 2009.
In this lab students will make qualitative observations of flame color, a property of metals, to identify unknown metals in salt compounds.
Learn about properties of matter through engaging, bitesize animated videos. There are many videos organised into these chapters: solids liquids and gases, elements compounds and mixtures, atomic structure, periodic table, ionic bonding, covalent bonding and metallic bonding.
Part two of the Mini Lecture "Quantum Mechanics" discusses Bohr's atomic model and the Heisenberg Uncertainty Principle and highlights the validity of both theorems for present-day quantum physics research.
This is an outline for how one could incorporate quantum mechanics into atomic structure. Students really seem to get hooked on it and it makes atomic structure way more interesting to teach.
Explore what makes a reaction happen by colliding atoms and molecules. Design experiments with different reactions, concentrations, and temperatures. When are reactions reversible? What affects the rate of a reaction?

How did Rutherford figure out the structure of the atom without being able to see it? Simulate the famous experiment in which he disproved the Plum Pudding model of the atom by observing alpha particles bouncing off atoms and determining that they must have a small core.
