In the periodic table, the vertical columns are called ‘groups’ and the horizontal rows are called ‘periods’. Those books were pulled out and elements looked up as they placed their. Periodic Table of Elements The periodic table is the tabular arrangement of all the chemical elements on the basis of their respective atomic numbers. The best part was how interested the kids got as they heard all the elements called out.
The result was this super fun Periodic Table of Elements BINGO Game I made it full classroom sized, so there are 30 different game boards. Mendeleev was unaware of the other work on periodic tables going on in the 1860s. The Periodic Table of Elements BINGO Game. As he attempted to classify the elements according to their chemical properties, he noticed patterns that led him to postulate his periodic table. In 1863 there were 56 known elements with a new element being discovered at a rate of approximately one per year (BBC.co.uk, 2015).Īfter becoming a teacher, Mendeleev wrote the definitive textbook of his time: Principles of Chemistry. Neither attempted to predict new elements. Another was Lothar Meyer, who published a paper in 1864 describing 28 elements.
The lack of spaces for undiscovered elements and the placing of two elements in one box was criticized and his ideas were not accepted. John Newlands published his Law of Octaves in 1865.
Other scientists had suggested in the 1860s that the elements display trends in their properties that could be used to put them into a table of periodicity. Using the table, he predicted the properties of elements yet to be discovered. He is credited as being the creator of the first version of the periodic table of elements. History of Mendeleev and the Periodic Tableĭmitri Mendeleev was a Russian chemist and inventor.
