  • The number of known elements kept increasing over time.

  • Proust gave an early hypothesis about hydrogen as building material.
  • Döbereiner grouped elements in triads.
  • The middle element in a triad had atomic weight close to the average of the other two.

  • Newlands arranged elements by increasing atomic weight.
  • The properties repeated at regular intervals of eight.
