Answer

Brief Explanations:

  • For the first question, Antoine - Laurent Lavoisier made early contributions. Johann Wolfgang Döbereiner proposed triads. John Newlands gave the law of octaves. Dmitri Mendeleev formulated the first widely - recognized periodic table. Henry Moseley related atomic number to X - ray spectra and refined the periodic table.
  • For the second question, originally elements were arranged by atomic mass in the periodic table, but now they are arranged by atomic number. Chemical properties are used to group elements in families but not for the overall arrangement order in the modern sense.

Answer:

  • First question: Lavoisier, Döbereiner, Newlands, Mendeleev, and Moseley
  • Second question: atomic mass
