Scholars build specific elements by creating a model of its atomic structure. Objects they can include are protons, nuetrons, electrons, orbits, clouds, charge, and mass number. Simulation ends with questions to challenge individuals'...

A study of the periodic table of elements doesn't have to be elementary! Deepen understanding of the building blocks of chemistry with an interactive periodic table. At first sight, the table looks like a standard reference page, but a...

In this chemistry worksheet, students read about atoms, their charges, and their parts; protons and neutrons. They examine how to determine atomic weight by looking at an example. They work online as they practice finding the atomic...

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.

[Free Registration/Login Required] Students explore how percent abundances of different isotopes affect the average atomic mass for that given element. Students form connections between the average atomic mass and a person's body mass....

[Free Registration/Login Required] Put the elements in the correct order on the table by using the information given in each of the element squares.

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...

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

An interesting and useful tool to practice recognition/calculation of atomic number, mass, and number of neutrons, electrons, etc. Can be used with all elements.
