How many elements are there in each triad of Dobereiner's system?

[tex]\sf\pink{ᯓ★}[/tex] According to [tex]\rm{\pink{Dobereiner's~ Law ~of ~Triads}}[/tex], each triad consists of [tex]\blue{\underline{\sf\pink{three}}}[/tex] elements with similar chemical and physical properties.

[tex]\sf\pink{ᯓ★}[/tex] [tex]\rm{\pink{Dobereiner}}[/tex] identified several triads, with the first one consisting of the alkali metals lithium, sodium and potassium.

[tex]\sf\pink{ᯓ★}[/tex] Other triads he identified included:

  • Calcium, strontium and barium (alkaline earth metals)
  • Chlorine, bromine and iodine (halogens)
  • Sulfur, selenium and tellurium
  • Iron, cobalt and nickel

[tex]\sf\pink{ᯓ★}[/tex] [tex]\rm{\pink{Dobereiner}}[/tex] noticed that the atomic mass of the middle element in each triad was approximately the average of the atomic masses of the other two elements.

[tex]\pink{\boxed{\sf\pink{໒꒰ྀིᵔ ᵕ ᵔ ꒱ྀི১}}}[/tex] So in summary, each of Dobereiner's triads contained exactly [tex]\blue{\underline{\sf\pink{three}}}[/tex] elements, grouped together based on their similar properties and the relationship between their atomic masses. The triads were not comprehensive though, as not all known elements could be fit into Dobereiner's system at the time.
