Periodic Table of Elements Placemat by M. Ruskin

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 nowDarmstadtium, 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.

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.

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 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.

This is an updated Periodic Table from the last one I bought (2002).

This one is dated 2010 and has some the newer elements named properly.

So don't go by the picture it is of the copyright 2000 version.

The colors seem brighter too of course mine is aged.

I have mine on the coffee table great conversation starter!

next to it I have the Star Chart version of placemat.

They compliment one another the very small next to the very large scale.

Great if you are going on "Jeopardy!" or studying for Chem 201.

(It keeps the beer glass from spoiling the table giant coaster!)
