LETTER TO THE EDITOR: “Cheese or Flu?” William B. Jensen
... LETTER TO THE EDITOR: “Cheese or Flu?” I would like to comment briefly on some of the points raised by Masanori Kaji in his recent review (Bulletin, 2007, 32, 58-59) of my book Mendeleev on the Periodic Law. Anyone who has studied the literature on Mendeleev knows that it is filled with contradictor ...

... example, germanium had not been discovered when Mendeleev constructed his table. After gallium, the next known element in Mendeleev’s time was arsenic. Arsenic did not match the chemical characteristics of carbon and silicon. Instead, arsenic matched the chemical characteristics of nitrogen and phos ...

... Mendeleev's table was not perfect, however. Arranging the elements by increasing atomic mass left three blank spaces in the table. Mendeleev boldly proposed that these blank spaces would be filled by elements that had not yet been discovered. Mendeleev was even able to use the patterns in his table ...

Dmitri Mendeleev
Dmitri Ivanovich Mendeleev (/ˌmɛndəlˈeɪəf/; Russian: Дми́трий Ива́нович Менделе́ев; IPA: [ˈdmʲitrʲɪj ɪˈvanəvʲɪtɕ mʲɪndʲɪˈlʲejɪf]; 8 February 1834 – 2 February 1907 O.S. 27 January 1834 – 20 January 1907) was a Russian chemist and inventor. He formulated the Periodic Law, created his own version of the periodic table of elements, and used it to correct the properties of some already discovered elements and also to predict the properties of eight elements yet to be discovered.
