Great for beginning chem students as it is large enough to read.

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.
