Description
Our version of the Periodic Table of the Elements is printed on a vinyl banner because it��s more durable than a laminated poster and it won��t tend to curl. 4-Significant Digits: In most cases, the average atomic mass is rounded to four significant digits because additional digits are extraneous much in the same way a math teacher has the students round pi to 3.14. Big Size: The framed portion of the table is 60�� wide by 40�� high. The width and height of the poster including the edges is about 63�� by 45��. Placed at the Top: The key for the classification of elements having similar properties is located at the top of the periodic table rather than the bottom.
