In this electron dot structures handout, new chemists read about electron arrangement and how to draw electron dot diagrams. They complete a chart with the mass number, atomic number, isotope notation, number of neutrons, and Bohr...

Lewis dot diagrams, Lewis dot structures, and electron dot diagrams are all the same thing. Young scientists learn how to draw Lewis dot diagrams and come to understand how dots and dashes represent valence electrons and ionic or...

This PowerPoint provides a complete recap of all the information needed for a unit on elements and the periodic table. The seventy slides cover the basic notation of elements, energy levels and ionization energies. The trends in the...

Where does an electron reside? Chemistry scholars determine an electron's "address," that is, what orbital it can be found in. This resource is both instructional and practical,  providing a thorough explanation of energy levels and...

If you need a clarification of the electron transport chain for your pupils, then this slide show will be a great help. There are nice images of the membranes and elaborations of chemiosmosis which will provide learners support with...

After drawing the valence electron distribution of 13 basic elements, there are spaces to draw 18 more complicated molecules.  For each molecule, there is space for a Dot structure and Lewis structure that best describes the...

In this electron worksheet students find values for the given letters including their subshells and in which orbital it occurs. 

It's all relevant, really. Individuals use the scientific method to learn more about elements, atoms, and their placement on the periodic table. They conduct experiments using materials common in nature to explore how elements affect our...

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....

In this drawing orbital diagrams learning exercise, 6th graders draw the electron configuration and orbital based on sublevels for given atoms. Students draw 8 orbital diagrams.

Couches, carpets, and even computer keyboards now advertise they are spill-resistant, but what does that mean? Scholars use physical and chemical methods to coat surfaces with thin films to test their hydrophobic properties. Then they...

Nothing says organization quite like a table. The third lesson in a six-part Mixtures and Solutions unit teaches young scientists about elements and the periodic table. They learn how the periodic table is organized and about the...

How did Rutherford determine that the nucleus was the center of an atom? Take a look inside the famous Gold Foil Experiment with an interesting interactive. Learners fire a beam of alpha particles at a nucleus containing variable...

In this atoms worksheet, students will review the characteristics of elements, atoms, and isotopes. Then students will compare the difference between ionic and covalent bonds. Finally, students will balance a chemical equation. This...

In this chemistry worksheet, students find the words that are related to atoms and molecules. The answers are found by clicking the link at the bottom of the page.

Students explore webpages to research the nature of atoms, including electrons, protons, and neutrons. This lesson is the first of a four-part series on static electricity. They see that static electricity involves + and - charges.

In this atomic structure instructional activity, students answer eleven short answer questions about the structure of atoms including the number of protons, neutrons and electrons. Students indicate the differences in isotopes of atoms...

In this molecules worksheet, students review the parts of an atom and use element mass to determine isotopes. Students give the group, period, and classification for the given elements. This worksheet has 6 short answer questions and 17...

If you are not part of the solution, then you are part of the precipitate. The presentation covers solutions, suspensions, solubility, dissociation, and acid/base reactions. This is the 19th lesson in a series of 26.

Simple in format and standard in content, this resource is an assessment of your beginning chemists' grasp of the atom. Using a periodic table of elements, they fill in a chart of missing chemical formulas, atomic masses, and numbers of...

Dispel the misconception that atoms are always little round balls! Illustrate changes in the electron cloud with an entertaining interactive. Pupils push and pull on the cloud by altering the charge on plates located on either side of...

Shock your physical science class using this video to teach the basics of static electricity. Electricity is defined,and electrons are differentiated from protons on an atom model. The use of hydropower and wind are explained as ways of...

Four diagrams of the atom and their subatomic particles and structures are given here and students should be able to complete the labels need to define the structures shown. The main structures defined are protons, neutrons, electrons,...
