Bigtime Signs Periodic Table with Real Elements Inside - 36x24-Inch Chemistry Periodic Table of Element - 118 Elements Chart for Classroom and Study Spaces - Durable Vinyl Science Posters - Black

Great wall decor

Great quality, very thick. My daughter wanted it for her bedroom and loves the colors!!

Teaching science is a joy, but when we began the unit on chemistry, the school did not have a periodic table. I bought this one and it's great. It's a perfect fit at a great price. It came quickly, and the kids were able to use it as a reference immediately.

Practical to tech and show big and nice colors

Bought for home. Good for memorizing the periodic table. I put it next to my bed.The material is strong. It’s one-sided (just in case you were hoping to hang it from the ceiling of your classroom for easy viewing or something…just in case!).There are metal holes in each of the four corners so you can hook it up to your wall if you want. (I taped mine because I don’t have such modern technology sadly…)Surprisingly, the poster is textured. Think super-thin yoga mat texture…I like it, but if you don’t like it, it doesn’t matter because it’s a poster so you’re probably not going to touch it with your bare hands most of the time right?Overall, 10/10.

I love this representation of the Periodic Table of the Elements. As a chemist it warms my heart. I purchased copies for some of my grandchildren, and framed one copy from my wall. The vibrant colors are beautiful and nicely group and highlight the various sections of the Table. I have one gripe, and hence only 4 stars instead of 5. The editing of the mass numbers is annoyingly inconsistent. With modern mass spectrometers, masses of individual isotopes are known with considerable precision. The Table's mass numbers themselves are weighted averages of the masses of all of the naturally occurring isotopes for each element, as determined experimentally from sampling nature. This usually means the weighted averages of the elements stable, as opposed to radioactive, isotopes. Several elements have only a single stable nuclide and therefore the mass numbers should be known with high precision, some examples would be F, Co, Mn, Au. Many other elements, such as N, Ni, Cr, and Ag have two or more stable isotopes, and therefore the listed mas numbers is the average masses of these isotopes weighted to there relative abundances. The Table values for these elements should be less precise than those of single nuclide elements. However in this table the masses of F, Co, Mn, and Au are listed to only three decimal places, while N with 2 isotopes, Ni with 5, Cr with 4, and Ag with 2 have masses listed to 4 decimal places. Why is this so? I purchased on 16"x 24" posters. If this mass inconsistency is corrected in the next addition, I may purchase one of the larger options to decorate one of my walls.

I use this all the time in my class. It is a very useful resource. I wish it was bigger.

This is huge, which worked perfectly on the wall of our lab room at a university.
