Students build atoms of elements 1-20. The entire set can be hung from the ceiling in order of the Periodic Table to be referred to throughout the Chemistry class/unit. This is helpful when teaching bonding and patterns of the Periodic...

This lesson focuses on atoms and elements including what they are, the chemical symbols for elements, and the placement of elements on the periodic table. A link to a test is provided.

This site provides a detailed overview of atoms. Content explores an atom's structure, as well as what ions are, how atoms bond, what compounds are (including how to name compounds), and what isotopes are.

As part of the General Chemistry Virtual Textbook, this site examines a list of related topics (in hyperlink format) on the atom and the Periodic Table of elements. Topics from light, particles, and waves to the Bohr model, quantum...

Short slide show provides basic information about drawing Lewis dot structures for covalent compounds. Starts with anatomy of the atom, and then shows the relationship between atomic particles and the Periodic Table of Elements. Offers...

Acting as a subtopic of the General Chemistry Virtual Textbook's section on Atoms and the Periodic Table, this site focuses specifically on the Periodic Table of Elements with information on the table's organization methods along with...

[Free Registration/Login may be required to access all resource tools.] Discusses elements and their different properties, the history of elements, and how atoms relate to elements.

Did you know matter is made up of atoms? In this article learn about the smallest unit of matter called the atom.

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!

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

Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.

Learn the fundamental properties of atoms in this article. Understand the definition of atomic number, atomic mass, and isotopes. [6 min, 50 sec]

Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.

A video and a short quiz on the parts of an atom, the periodic table, and molecules.

The number of protons in the atom of an element determines its place in the Periodic Table. The number of electrons in an atom is the same as the number of protons. These electrons are arranged in shells or 'energy levels' around the...

Acting as a subtopic of the General Chemistry Virtual Textbook's section on Atoms and the Periodic Table, this site discusses the limits associated with classical physics. Topics covered include light and heat with additional information...

The interactive activity examines the Periodic Table of Elements. Learners answer questions about the number of protons, electrons, neutrons, or nucleons that an atom of an element contains.

A chemistry tutorial highlighting historical development of the atomic theory of matter and the periodic table of elements.

Find out the basic characteristics and main properties of all matter.

[Free Registration/Login Required] This flipchart introduces fifth graders to atoms and elements. Key concepts include atoms, parts of the atoms, elements, and the periodic table. Opportunities for student participation are included...

This instructional activity introduces students to scientific models. The students will learn how models of the atom have changed as new evidence is gathered. The students will also learn about the current model of the atom. Each student...

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...

A fun way to learn about the periodic table! This interactive table allows students to investigate the basic information of an element as well as explore group and family characteristics.

Provides definitions and characteristics of elements, compounds, and mixtures, and gives an animated image of each.
