What to Focus On

  • Classification helps in remembering and comparing elements.
  • Boyle defined an element as a substance that cannot be decomposed into a further simple substance by physical or chemical change.
  • 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.
  • His table had only 56 elements.

Common Mistakes to Avoid

The periodic table is arranged in increasing atomic weight in the modern form.

Atomic number means atomic mass or atomic weight.

All elements in the same group have the same number of shells.
