In this activity, students use a map of electron configuration and bingo chips to configure electrons for elements that are given on a problem card. Students will see patterns of elements and their valence electrons in relation to the...

Acting as a subtopic of the General Chemistry Virtual Textbook's section on Atoms and the Periodic Table, this site discusses the properties of the atoms individually in relation to the main group elements of the Periodic Table.

Analyze the electron configuration of the of the first twelve elements on the Periodic Table.

Joseph John Thomson, better known as J. J. Thomson, was a British physicist who first theorized and offered experimental evidence that the atom was a divisible entity rather than the basic unit of matter, as was widely believed at the...

Looks at the scientists who developed the model of the atom by building on previous scientists' discoveries about its structure.

This StudyCard activity enables students to review the key contributions by scientists and philosophers towards are current understanding of the atom. It also allows students to review characteristics of the major atomic models.

Learn about Thomson's cathode ray experiment and the plum pudding model and Rutherford's gold foil experiment.

Simulations to show students the nature of chemical bonds. Simulations include an explanation of stereochemistry, atomic orbitals, chemical polarity, formation of an atom, and a summary quiz.

View the approximate locations of electrons in valence shells 1s through 4f.

In this lab, young scholars investigate basic electron structure by making a model using pennies and different sized filter papers.

How did Rutherford figure out the structure of the atom without being able to see it? Simulate the famous experiment in which he disproved the Plum Pudding model of the atom by observing alpha particles bouncing off atoms and determining...

A brief explanation is provided for designing a stable atom. You can also refer to a labeled model of a carbon atom. This resource also has a link to an atom building activity.

A summary of the achievements of J. J. Thomson, Ernest Rutherford, Niels Bohr, and Erwin Schrodinger.

Learn about the models of the atom that have been proposed throughout history. Presents Democritus, John Dalton, J.J. Thomson, Ernest Rutherford, Niels Bohr, and the modern theory of the atom. Sections are accompanied by journal...

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 part of an overview on quantum theory, this section of the site answers the question, "How did Bohr's theory save the planetary model, for a while?" A section below also discusses the primary problems with Bohr's theory.

Basic properties of the element Gadolinium Includes Bohr model.

[Free Registration/Login may be required to access all resource tools.] Students learn about the important discoveries of subatomic particles, and how they led to our current understanding of the atom.

Presented is an overview of atomic theory concentrating on the experiments of Ernest Rutherford.

[Free Registration/Login Required] Neon lights are a type of discharge tube. Observe how electrons create colored light in a hydrogen gas discharge tube. Can you figure out why hydrogen's emission spectrum contains more than one color of...

A wonderful PBS biography of a great man. This contains many personal touches, yet does a fine job of describing Bohr's scientific work. But it's best at Bohr the man. Nice quotes, one in the middle, one at the end.

[Free Registration/Login may be required to access all resource tools.] A complete, web-based, multi-media textbook covering a wide variety of Chemistry concepts.

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...

Enrico Fermi was a titan of twentieth-century physics. He outlined the statistical laws that govern the behavior of particles that abide by the Pauli exclusion principle and developed a theoretical model of the atom in his mid-twenties....
