Understanding Oxidation Numbers

Colored boxes with white font present the basic periodic table of elements to your young chemists. All of the basics are included: chemical name, symbol, atomic number, atomic mass, and the number of electrons in each orbital. A brief...

Four activities immerse beginning chemists into the world of elements. They examine the periodic table, use cobalt hydroxide to learn about chemical formulae and valence electrons. Also, they name binary compounds and examine the...

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,...

Explore and control the building blocks of atoms! Physical science superstars add and remove subatomic particles to create atoms and ions with an easy-to-use interactive. An alternate activity includes an assignment that focuses on the...

What does an atom look like? The instructor in a tutorial video models how to use the periodic table to determine the number of subatomic particles. He then uses the number of electrons to create an orbital diagram. Finally, Groves...

Demonstrate the steps to drawing electron configuration diagrams. A video lesson shows how to use the periodic table to determine the number of electrons in an element and then create the diagrams. The instructor leads your class through...

Electron location accounts for many properties of an element. A video lesson describes how to create electron dot diagrams. The instructor discusses electron shells and the number of electrons in each.

Acting as a subtopic of the General Chemistry Virtual Textbook's section on Atoms and the Periodic Table, this site discusses a series of topics related to electrons including atoms that have only one electron, effects of...

Recognize the atomic number and mass number of an atom and how they are linked to the electrons, protons and neutrons of an atom. [2:05]

This is a tremendous overview of the tiny atom. Journey through the history of human understanding of this basic building block of matter. Examine each of the sub-atomic particles in detail: neutrons, protons, electrons, quarks. Peruse...
