Mendeleev’s Periodic Table:
(i). Elements are arranged in the order of increasing .
(ii). There are nine vertical columns called .
(iii). There is no place for noble gases.
(iv). There is no place for isotopes.
(v). Transition elements are placed together in group .
(ii). There are nine vertical columns called .
(iii). There is no place for noble gases.
(iv). There is no place for isotopes.
(v). Transition elements are placed together in group .
Modern Periodic Table:
(i). Elements are arranged in the order of increasing .
(ii). There are eighteen vertical columns called .
(iii). Noble gases are placed on the right hand side of the table.
(iv). are kept at the same place because their atomic number is same.
(v). Transition elements are placed in the of the long period (Group 3 to 12).
