It was the first textbook devoted to chemistry. In 1789, Antoine-Laurent de Lavoisier wrote the Elementary Treatise of Chemistry. Scientists used this definition until subatomic particles were discovered. He defined an element as something that cannot be broken into smaller parts by a chemical reaction. Robert Boyle developed the definition of an element around 1650 that was used for 300 years. Below are some of the people whose work contributed to the formation of the periodic table. Scientists continue to find elements and learn about them today. This led to the discovery of new elements. At this time, people began conducting chemical experiments. The work that led to the periodic table began during the Age of Enlightenment. Symbols in black (solid), blue (liquid), or red (gas) elements (at room temp.) Synthetic elements are in gray.The study of the elements goes back to ancient times.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. I’ve produced a printable periodic table for posting on the wall in my classroom (updated April 2017).
