Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!

This collection of videos, animations and documents comes from the NCSSM AP chemistry online course. Chapter three part one provides practice and demonstrations related to atomic structure in chemistry.

This collection of videos, animations and documents comes from the NCSSM AP chemistry online course. Chapter eight provides practice and demonstrations in chemistry related to Atomic Structure, (this is part two).

This is a laboratory exercise designed to allow students to further investigate the light spectrum. This lab is used to have students view the light spectrum first hand as opposed to using lecture alone.

Simulate the original experiment that proved that electrons can behave as waves. Watch electrons diffract off a crystal of atoms, interfering with themselves to create peaks and troughs of probability.

Drawing two dimensional images of an atom.

This activity is a simple way for students to understand the basics of electron energy levels, a fundamental atomic concept.

This activity is an observation lab where students observe the colors emitted by various metal ions in salt solutions.

This activity is a guided inquiry activity where students take simple measurements and use unit analysis to determine the thickness of a sheet of aluminum foil, the volume of an aluminum atom, and the radius of an aluminum atom.

This is a self-contained book-on-the-web course on basic astronomy, Newtonian mechanics, the sun (and associated physics), and spaceflight and spacecraft. covers elementary astronomy, Newtonian mechanics, the Sun and related physics and spaceflight. Also included are a Spanish translation, 46 lesson plans, a short but complete math course (algebra + trig), teachers' guides, glossary, timelines, 345 questions (current tally) by users and their answers, over 100 problems to solve, and more.

This lesson plan explores the fundamentals of atoms and their structure. The building blocks of matter (protons, electrons, neutrons) are covered in detail. Students think about how atoms and molecules can influence new technologies developed by engineers.

A three-quarter general chemistry sequence primarily for science, pre-professional, and engineering students. The CHEM& 161/162/163 series introduces the basic concepts of chemistry: atomic structure and bonding, periodicity, physical measurement, quantitative relationships, chemical reactivity, oxidation and reduction, stoichiometry, ideal gas laws, aqueous solutions, colligative properties, intermolecular forces, structure of matter, equilibrium, acid/base topics, kinetics, thermodynamics, electrochemistry, nuclear chemistry, qualitative analysis, d-block metals and coordination chemistry, and an introduction to organic chemistry.

In this activity, students make a model of a lithium atom using gumdrops and toothpicks. Using this model, they investigate the makeup of an atom, including its relative size. Students also practice adding and subtracting electrons from an atom and determining the overall charges on atoms.

Introduction to Solid State Chemistry is a first-year single-semester college course on the principles of chemistry. This unique and popular course satisfies MIT's general chemistry degree requirement, with an emphasis on solid-state materials and their application to engineering systems.

This activity is an indoor structured inquiry lab activity where students will use various types of M&Ms as a model for isotopes. Students will design a procedure to determine average atomic mass.

Isotopic Pennies is an activity where students use what they have learned about isotopes and weighted averages to solve a new challenge.

This activity is a series of game-like lessons that assist the student in developing the logic skills needed to read mass spectrometer output and formulate the identity of an unknown molecule. As students endeavor to identify the unknown they must apply fundamental chemistry knowledge including formula mass, isotopes, periodic table, relative abundance, interpreting graphs, organic chemistry, ionization, bonding rules, and structural formulas. Based on an activity presented by Olaf Runquist, Professor, Hamline University.

This unit covers introductory concepts of mixtures and solutions. Students think about how mixtures and solutions, and atoms and molecules can influence new technologies developed by engineers. The first lesson explores the fundamentals of atoms and their structure. The building blocks of matter (protons, electrons, neutrons) are covered in detail. The next lesson examines the properties of elements and the periodic table one method of organization for the elements. The concepts of physical and chemical properties are also reviewed. Finally, the last lesson introduces the properties of mixtures and solutions. A comparison of different mixtures and solutions, their properties and their separation qualities are discussed.

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.
