Ever looked at a periodic table and wondered what all of the numbers beside each symbol mean? This very simple interactive activity will explain them to you. Simply roll the mouse over each feature to find out what the number is referring to.
Start the Atomic notation animation
In this interactive animation, click on an isotope button (protium, deuterium or tritium) and watch how the animation changes. What do you observe?
Start the Isotopes animation
This interactive shows an alternative way of representing the electron configuration (to the shell model). While not required in the WA syllabus, you may find it useful background information to your study of electron configurations. The interactive periodic table allows you to click on each element and receive pictorial information on how they are configured.

Orbital energy diagrams
This interactive activity compares a hydrogen atom with a typical multielectron atom to show you how their orbital energies differ. Click on each of the four descriptions listed below the diagrams, and watch the examples.

Periodic table and order of filling
This interactive shows the order of filling of hydrogen compared to multi-electron atoms using the s, p, d, f notation. Note—this is not required for the WA syllabus but is useful in providing a deeper understanding of electron configurations. In this activity, click on each of the red arrows beside the rows of elements in the periodic table. Observe how the orbital filling progresses.

Interactive periodic table
Want to know some specific information about an element? (Is it a metal or non-metal? What is its atomic mass? Or its melting point?) This detailed periodic table allows you to select from drop-down menus in order to collate the information you need.
