Interactive Periodic Table
LEARNING OBJECT Investigations into periodicity of elements - electronegativity and ionisation energy.

Students are given definitions and explanations of electronegativity and first ionisation energy.

Ptable has a history stretching back to September 1997, a year before the founding of Google. It was introduced as a piece of HTML artwork and published to the web October 1, 1997

Excellent site featuring an interactive periodic table. Clicking on each element gives very detailed information about that element in the Periodic table. The information is organised in headings:
• Wikipedia
• Properties
• Orbitals
• Isotopes
• Compounds
It is possible to have the table without names or to show weights, electrons, and in wide format.
The table is easy to navigate and could be used by teachers to demonstrate features of the elements and the periodic arrangement. It could also be sued by students for homework and for revision. The website also suggests possible projects.
With help from the American Association of Chemistry Teachers and American Chemical Society, Ptable has sponsored the creation of new lesson plans developed by chemistry teachers which take advantage of the site's in-depth interactivity. Using these free lesson plans, you can engage with the periodic table in ways which were previously impossible. Investigations
In this activity, students will use the online periodic table to investigate a number of chemistry concepts. Students will use this online resource to explore information about the elements, including historical data, physical properties, periodic trends and more.
Exploring Elements
In this project, students will select an element and then use to explore aspects of the element including its periodicity, electron configuration, history, and uses in industry.
Making Connections between Electronegativity, Molecular Shape, and Polarity
In this activity, students will find the electronegativity values of a variety of elements, draw the Lewis structures of selected molecules that are made with those elements, and identify the molecular shape of each molecule. Students will then be asked to determine if the molecules are polar or nonpolar based on the electronegativity values of the atoms and the molecular shape.
This is an excellent resource for chemistry teachers and their students. It provides a periodic table in printable format but more importantly in interactive format that allows reinforcement of important basic concepts. The website also allows feedback that may lead to further developments.
The table has no pictorial forms – it is just the table with symbols and the various add-ins. This may limit its appeal to visual learners but does not detract from its overall usefulness.
The table can be purchased in large poster formats.
The tool allows students to work with data and relate it to the elements and the periodic table.
It can be used for homework or revision activities.
The interactivity gives more practice than just reading a paper copy and looking at static data tables.
It can also be used for comparison with other versions of the periodic table.
The interactive periodic table I used is found on the Royal Society of Chemistry webpage ( It is very user friendly. It has a nice clear layout that is colour coded. When you hover the mouse over an element it gives you a brief synopsis on that element - key isotopes / electron configuration / density / 1st ionisation energy / supply risk. When you click on the element you get a huge amount of information for each element - discovery date / who discovered it / origin of name / large fact box and then a list of sub headings that you can click on for more information - uses and properties / history / atomic data / oxidation rates and isotopes etc. There are also a number of filters at the top of the web page that you can change, such as, temperature, classification, groups, blocks and periods. When you change these filters the colour of the elements change accordingly.
I would definitely use this resource with my classes, it starts with basic information but as you progress with your study of science you can get more and more information from this page. I would use this for project work on an element and also when teaching many different aspects of chemistry, such as, general layout of the periodic table, bonding, assigning oxidation numbers etc.
