The Structure of Atoms

Teaching young scientists about atoms is no small task, but this series of worksheets will make it a little easier. From creating and labeling Bohr models, to identifying information provided in the periodic table of elements, this...

Get down to basics with these worksheets on the structure of atoms. Challenging young chemists to identify information from the periodic table and create Bohr diagrams and Lewis dot structures for different elements, this resource would...

In this atom activity, chemists learn how to determine the number of protons, neutrons and electrons in an atom using the atomic mass and atomic number. They complete a chart of the subatomic particles and use marbles to represent...

This is a basic presentation that can be used to introduce your budding chemists to the structure of an atom. It gives step-by-step examples of a few atoms, showing their particles as well as their chemical formulas and the associated...

The first nine slides visit the history of our understanding of atoms. The next several outline the structure of atoms. Subatomic particles, electron configuration, and diagramming methods are introduced. This is a neatly organized...

What's smaller than a kiwi seed? Atoms! Basic atomic structure is detailed for beginning chemists in a light-hearted animation. Protons and neutrons are explained as part of the nucleus, and so are electrons that encircle the nucleus....

Explore and control the building blocks of atoms! Physical science superstars add and remove subatomic particles to create atoms and ions with an easy-to-use interactive. An alternate activity includes an assignment that focuses on the...

Students research the element of carbon, its composition, and the importance of carbon to life on earth. Then they design model mobiles of carbon atoms to demonstrate their understanding of the configuration of protons, neutrons, and...

From ancient Greek philosophers to early American Quakers, people have sought to understand the composition of matter for millennia. Follow along with this video as it explores the long scientific journey that eventually led to the...

An engaging simulation encourages scholars to discover if the Bohr model of an atom is correct. They shoot light at a hydrogen atom in various conditions to see which of the many models is plausible or inadequate.
