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.

This activity allows students 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 the...

This slide and audio book shows how to relate mass to a number of particles by using many formulas, examples, and real life scenarios. View the weighted average calculations, Avogadro's number, the atomic mass of carbon, and molar mass.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will identify three methods for measuring the amount of matter in a sample. They will define the mole and its relationship...

Dutch version of the well-known "Particle Adventure" physics website that teaches students about atoms, mass, particle physics, and quantum physics. The site discusses theories related to physics and provides other links related to the...

This simulation allows students to understand relative binding energy.

This subtable lists and describes the six alkali metals of the periodic table of Elements. Related links are provided.

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

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

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

You will be presented with three different isotopes of the same element. See if you can calculate the atom's average relative mass.
