Bigtime Signs Periodic Table with Real Elements Inside - 24x16-Inch Chemistry Periodic Table of Element - 118 Elements Chart for Classroom and Study Spaces - Durable Vinyl Science Poster - Black

Great quality print and it is very durable. The rings are reinforced well.

I'm giving this product 5 stars because of its excellent quality. It's also beautifully colorful. Sadly, I will have to return it for two reasons. Since this is a "poster", I ordered a DACRI Magnetic Poster Hanger (36") to display it. 1. The poster is mailed rolled up. It is rolled up laterally; my poster hanger attaches to the top and bottom of the poster (which is heavy vinyl) so the sides curl inward and do not hang flat. 2. The poster has a thick grommet at all four corners, so the fit of the magnetic hanger pieces is a bit funky. I will replace this poster with one that already comes framed.

Stunning and Colorful!

Awesome. Big vinyl poster of the table of elements. What else is there to say?

Love it. Very nice quality

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.

Didáctica y decorativa

Super nice very impressed with vinyl fabric with garments for different ways of hanging we used blue painters tape to hang up easy to read a beautiful display very happy
