Absolutley shocking website with disgusting contents. The other day my youngest asked for an online periodic table in order to complete his hw and my oldest, with a sly smirk, reccomended "" . Unbeknownst to me this was no homework aid at all and is filled with gore, violence and even nudity. That was the day I lost timmy for when he went back up to his room and opended this disgusting page his young and innocenct mind was corrupted beyond repair and I don't think he will ever heal. The worst thing though is that this website may never be taken down seeing as it hides itself under the guise of being an innocent "scientifical research page". Apart from the occasional cheeky visit by yours truely this website will never be used within my walls again. Please never let your children touch this website.

Our review:

Kids say (1 ):

Ptable is awesome for kids truly interested in chemistry or who have a parent who wants to get them interested. The sheer quantity of information about each element, from atomic number to abundance in the universe, is quite enough, but then add color codes, dynamic and interactive data, links to a complete set of videos and podcasts from distinguished sources, and striking and orderable images and posters, and you've got a website with some serious depth. Need more? Creator Michael Dayah provides a video demo of the site (though it's a bit on the speedy-yet-cursory side), plus he outlines the site history, navigation features, sources, search techniques, and troubleshooting tips.

It can be tricky to discern the selected element, and, if you're looking for a place to get a younger kid started, the Jefferson Lab site is more plain and accessible, plus it has games, puzzles, and a student zone ( On the other hand, if you want to launch your chem-head kid into a new world of understanding, Ptable, in Dayah's own words, makes "Mendeleev's creation come alive."

Did we miss something on diversity?

Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.
