This page displays the Periodic Table of Elements and allows you to click each individual element for a page that displays in-depth information about that particular element. There are also links to many different games and learning...

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

This essay, written for Teachers' Domain, describes the foresight and pattern recognition that Russian chemist Dmitri Mendeleyev used to develop the modern periodic table of elements.

This interactive periodic table developed for Teachers' Domain provides detailed information about the chemical properties of elements and illustrates the electron configurations that determine those characteristics.

A very detailed look at the element Gallium, a member of the Boron Group.

Learn how to read the periodic table of elements as you solve these Math questions about the number of protons, neutrons, electrons or nucleons in an atom of an element. You can choose how many questions to answer, and how complex they...

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

Find out if you know enough about atoms to build them. The goal of the activity is to build an atom of a particular element by dragging the correct numbers of neutrons, protons and electrons into the atom.

Learners will use a graph of the relative abundance of elements in the Universe to determine relationships between size of the atoms and their abundance.

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...
