WebbThe Structure and Meaning of the Periodic Table: Periods. The periods of the periodic table are the rows that run from left to right in the periodic table. The elements are not arranged in these because of similar properties but because of their increasing atomic number from left to right. 40. WebbIn 1863, chemist John Newlands organized the 56 elements into 11 groups based on their characteristics and similarities. In 1869 Dmitri Mendeleev started the creation of the periodic table. He predicted the discovery of more elements, and left spaces open in his periodic table for them. In 1907 it was discovered that thorium and radiothorium, products of radioactive decay, were physically different but chemically identical; this led Frederick Soddy to propose in 1910 that they were the same element but with different atomic weights. Soddy later proposed to call these elements with complete chemical identity “isotopes“. the pad and how to use it movie
