You can't tell by the title, but this is a functional periodic table of elements. Incorporating bright colors, lucid text, and easily operated features, this application serves as a valuable reference tool for your chemistry class.

Students study the difference between types of ionizing radiation and how elements are transmuted. They determine that radiation is normal and surrounds us. They calculate the amounts of alpha, beta and gamma radiation emitted from a...

In this Bohr atom worksheet, students complete a table with the number of electrons of the element, the electron configuration, the mass number, the number of protons, the number of neutrons, the element, the symbol and the isotope...

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...

Starting with a recap of atomic structure, these slides continue by comparing different isotopes of uranium and explaining which are stable and which have a decay period and emit alpha or beta particles. Gamma decay is just mentioned on...

Is your class in a quandary over quantum numbers? Change things up by adding games to the mix! Science scholars discover the shape, number of electrons, and number of orbitals in the s, p, and d sub-shells using an interactive.

In this quantities in chemistry instructional activity, students solve 13 review problems about percent composition, significant digits, the mole, simple and molecular formulas, balancing equations, stoichiometry, limiting reagents and...

For this chemistry calculations review worksheet, students solve 33 review problems about titrations, precipitates, pressure and volume of gases, combustion reactions, heat of combustion, molar concentrations and molecular formulas.

For this chemistry worksheet, students use the periodic table of elements in order to identify the common elements. The detail is very detailed.

Eighth graders investigate the different elements of the Periodic Table. In this chemistry lesson, 8th graders pick an element to research, then present to the class using a powerpoint presentation or a poster.

In this science worksheet, students use a periodic table to complete the first four rows of a chart. Students use the Internet or research books to complete the last column.

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.

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 may be required to access all resource tools.] Students explain the workings of a mass spectrometer, and describe how this device is used to determine average atomic mass.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will be asked to define atomic number, mass number and understand how isotopes differ from one another. They will be able...

Tutorial explains isotopes, atomic weight and how isotopes can be detected using mass spectrometry. Examples are given.

A tutorial describing average atomic mass and how it is calculated.

This activity allows young scholars to gain an understanding of the relationship between the mass and relative abundance of an isotope and its effect on the average atomic mass of the element. Students will be given a random sample of...

In this activity, students apply what they have learned about weighted averages, isotopes, and systems of equations to a new situation - coins in a sealed container. They learn some historical information regarding the composition of...

[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....

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

Students investigate the structure and parts of the atom, and learn about atomic mass and atomic number. They also explore the differences among solids, liquids, gases, and plasma.

Students explore the periodic table and learn the basic information given for elements: the name, symbol, atomic number, and atomic mass for each element.

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