Mendeleev was the inventor of the periodic table. He organized all the known elements into the periodic table based on atomic number. He was also able to predict the existence â¦ of elements that had not yet been discovered based on gaps in the table he created.
I think that there was a number of things that led to Mendeleev not including the âinert gasesâ in his table. The main one is that Mendeleevâs studies were about the way elements react with other elements to form new substances, as their reactivies were used to determine their atomic masses.
