Color-coded background for element families/groups.Includes updated names and symbols adopted by IUPAC through 2016.Element name, symbol, atomic number, and atomic mass.The final dimensions are about 6 feet wide and 3-4 feet tall. Each individual element block is then taped together on the back or glued onto a backing material. I had mine printed at Amazon Prints for about $11.00, though many local or chain shops may have special deals that would allow you to get this printed pretty cheaply.
This version is designed to be printed in color on 4×6 photo paper (I chose matte finish for less glare, but glossy might work too). I thought other teachers might wish to do the same, so I’m making it available here. We have excluded elements above 108 on this periodic table for the simple reason that the larger elements don’t really exist in the real world.I’ve produced a printable periodic table for posting on the wall in my classroom (updated April 2017). You might find a table of elements showing element 115 or even 118 elements total. There is a Netflix documentary about this topic entitled Bob Lazar: Area 51 & Flying Saucers. The elements above 92 are strange, like for example element 115 that was reportedly found at Area 51. The parenthesis are a scientific way of saying this number is guesstimated, at best, and we really don’t know much about these elements because they are artificial and tend to disintegrate rapidly. You might note in the periodic table the mass numbers are in parenthesis for elements 93 and above. At least you won’t be finding any in this lifetime. As such, elements above 92 don’t really exist, except under special laboratory conditions. All elements above atomic number 92 are created artificially in laboratories, and generally they are extremely unstable and tend to disintegrate rapidly. As such, it’s highly unstable and unable to exist for very long. It is element 94, making it bigger than uranium. In 1940, a new element, plutonium, was created in a laboratory. Element 92 is uranium, the biggest element that occurs naturally on Earth. Before the year 1940, it was believed that only 92 elements existed. (See the original work of Dmitri Mendeleev here.) At that time, scientists were still discovering new elements almost every year. The original table of the elements, credited to Dmitri Mendeleev in 1871, had only 56 elements. The table of elements shown here has 108 elements.
