The creator of this collection of chemistry slides is clever! Electron configuration is explained as, click-by-click, orbitals are displayed and then each is subsequently filled with the proper amount of electrons. After the progression,...

Here is a six-page exploration that will spark interest in the periodic table of elements. After reading a diagram-supported explanation of the periodic table's organization, pupils answer questions to familiarize themselves with it. To...

Students explain how the elements are arranged in the periodic table. In this chemistry instructional activity, students determine the subatomic particles for certain elements. They research the physical and chemical properties of an...

In this writing nuclear reactions worksheet, students read about nuclear equations for alpha decay, beta decay and positron emission. They are given the rules for writing nuclear reactions and a sample problem.

For this nuclear power worksheet, students read how atoms can be changes and are unstable. Students compare 3 kinds of radiation and the difference between fission and fusion. Then students complete 10 matching and 2 short answer questions.

In this atom worksheet, high schoolers answer 31 multiple choice questions about the structure of atoms, the periodic table, the reactivity of elements, orbital diagrams and the families of elements.

In this minerals and rocks activity, students answer questions about the chemistry of minerals, scratch tests, rocks and the rock cycle, and erosion and deposition.

Eighth graders investigate the different elements of the Periodic Table. In this chemistry lesson, 8th graders pick an element to research, then present to the class using a powerpoint presentation or a poster.

Students research elements on interactive Internet periodic tables, take notes using Inspiration software, and write descriptive paragraphs with graphics. They create presentations.

In this atoms activity, students answer four different sets of questions related to atoms (fill in the blank, multiple choice, word puzzle and true and false).

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will be asked to define atomic number, mass number and understand how isotopes differ from one another. They will be able...

This is a chart of the elements including the atomic mass, atomic number, symbol, half-life, and more.

This lesson explains many basic concepts of atomic structure. It starts with atomic mass and number and then works up to more sophisticated information on electron configuration and how each element fits into the Periodic Table.

This site provides an overview of elements and atoms, the building blocks of matter.

Engaging and very informative article that explains what elements are, some of their history, how they are represented, the categories of elements, the periodic table, and how they are structured and classified.

Review atoms with this slideshow. You can choose to listen to the review or read the accompanying text. At the end, play the game to review the basics of atoms that you have just learned about. You may play the game as many times as...

Learn about radioactivity, the different types of radioactive decay, isotopes, and half-life of a radioactive element. Includes a long chart listing radioactive elements, atomic number and mass number, decay type, and length of half-life.

[Free Registration/Login Required] Learn what makes each element unique by building the mystery atoms in the periodic table.
