The group 18th of periodic table which is composed of Noble gases mainly was missing from the Mendeleev's periodic table. The reason for this is that Noble gases are least reactive, therefore, it was difficult to predict such elements which do not react with other elements. Hence, it was not part of that table.❤ʜᴏᴘᴇ ɪᴛ's ʜᴇʟᴘs❤
