This placemat is the perfect balance between a regulation sheet periodic table and a poster size.
It is 17.5 inches by 12 inches and coated in really heavy plastic. Has Atomic number, symbol, name, atomic weight, valence shell configuration (and big enough to actually read), boiling, melting point, density, crystal structure and is color coded. It does stop at 112 and we are up to (in theory 118) but that is not going to be addressed in most beginning chem classes.
Also 110, 111 and 112 do have names now Darmstadtium, Roentgenium and Copernicium respectively. So a new update would be nice (hence one star off, as it was published in 2000) , but again, for beginning students this will not be an issue.

*Update of review
It has been updated, I just ordered a second as my first kid is going off to college to major in chemistry, and the second kid will need her own periodic table at home. The new version has 114 and 116 and the names for 110-112 are added. The rest up to 118 are not listed.

However, it does have a shinier laminate, which my kids did not like as much. The old version had a non shiny surface.

After buying other periodic table placemats and posters, this is by far the best. Most of the others were flimsy and uninspired - more like posterboard. This is a real placemat with bold colors and solid finish that will last.

I am a 1st year nursing student and knew nothing about the metric system. This has been such a big help to me and I did not feel that I was using a toy. A definitely good learning tool!

I love these learning place mats, we have several of them. But I really, really wish that "Learning About Money" showed coins as their actual sizes. (OR at least in proportion to each other) I find it confusing and so does my son. And, while it is interesting to see the Half Dollar coin and the Golden Dollar coin, I think that they should have been footnotes. That would leave more space for "every day" money.

What a great idea to have a placemat of the Periodic Table! I bought this placemat to help my high school age daughter with her chemistry homework. It is very sturdy, easy to read, and extremely helpful. SInce it is colorful and fairly large, it is also hard to misplace. We leave it on the dining room table and use it for chemistry homework or mini-lessons whenever needed. One side is color coded to help students rapidly identify the alkali metals, alkaline earth metals, transition metals, nonmetals, noble gases, and metalloids. It also lists the symbol, name, atomic number, atomic weight, valence-shell configuration, boiling point, melting point, density, and crystal structure for each element. The back side of the placemat is in black-and-white and lacks the element names & symbols. This side can filled in with an erasable marker and used to help memorize the Periodic Table.

This is a wonderful placemat. Even my adult sisters are re-learning from it. As a placemat, it won't get ripped or dirty as easily.

I bought this to make a set of 4. This was my 4th choice and was combined with a world map, US map and a place mat with all the presidents. Two 10 year olds grabbed this one right away before dinner and began quizzing each other about their times tables, then flipped it over and began completing back side with a dry erase marker. All the place mats have been fun,educational,durable and stimulate dinner conversation.

I bought four of these placemats for my table. My son is in eighth grade. He is studying chemistry in his science class. These placemats kept him talking about chemistry throughout dinner. They are thick quality and can be wiped off easily with a damp cloth. The front shows the full periodic table. The back shows the periodic table without the element symbols written in, so they can be used to quiz the student. The instructions state a dry erase marker can be used to write on them and will wipe off easily. My son points out that some information is missing such as the boiling point of francium and radium, the density of francium, the density and boiling point of astatine, and finally the boiling point of arsenic.

I have a 2 year old and a 6 month old. I was at lunch with a girlfriend who has a three year old boy who was reciting to me all of the presidents =IN ORDER!!! I asked how in the world he knew that and she said she had these educational placemats and every meal he asks who everyone is and learns them from the constant exposure. I decided what a perfect way to make her meals educational and fun! I really liked that there were all sorts of money on there and when she gets older, there are even activities she can do like figuring what combinations of money makes certain amounts. I will just be so proud when she starts being able to pick up money and knows which is what! I HIGHLY recommend it!

I am a home-school educator and my son is currently taking chemistry. This laminated mat is absolutely great and he has indicated what an asset it has been throughout the coarse. One side of the mat is colored and the other is in black-and-white. Electron configurations of elements are listed, as well. To me this is a must-have for all high-school chemistry students and the lamination make it higly durable.
