The diagram represents an early periodic table firThe diagram represents an early periodic table first published in 1865 by G. Newlands. It lists 62 elements in atomic weight order arranged in 8 vertical columns called “octaves”. (a) one complete family of element is missing from this table. Name this family (or group) of elements and briefly explain why it was not included. (b) Li, Na, K, Rb and Cs are all listed in the same family. Briefly describe one property these five elements have in common. (c) This table suggests that Cu should also be a member of the family listed in (b). Briefly describe one property of Cu which is not possessed by any of Li, Na, K, Rb or Cs. (d) Uranium was misplaced because its atomic weight was wrongly calculated. The chloride of uranium, whose formula was thought to be UCI_2, was found to contain 62.9% uranium by weight. Calculate the atomic weight of uranium from these data. (The atomic weight of chlorine was known to be 35.5). (c) What name is given to the zone of the periodic table on the Data Sheet which includes uranium?Show transcribed image text The diagram represents an early periodic table first published in 1865 by G.
