The modern periodic table was arranged by russian chemist dmitri mendeleev in 1869 and is a tabular arrangement of the chemical elements mendeleev was interested in formulating the known chemical elements into a identifiable system and he was not the only one. The periodic table of chemical elements (abbreviated periodic table) is well known to anyone who has ever entered into the scientific laboratory or classroom. What is truly extraordinary about this work is that the scientist predicted the existence of certain the properties of these elements were surprisingly similar to those described by dmitri mendeleev earlier, which left no doubts about the importance of. Mendeleev made an early periodic table. Using his periodic table, mendeleev predicted the existence and properties of new chemical elements. What did chemists use to sort elements into groups? In other words the elements of what we now call a 'period' were listed vertically by mendeleev. Animation of the periodic table. It is at once evident that such regularities very much simplify the study of chemistry. He studied science in st.
