A triad has three elements from the Periodic Table that have something incommon weather the number of valence atoms or the number of protons and electrons.
the main defect of' dobereiner's triads is that he put the chemically dissimilar elements in the same triads (dahal.ramchandra@gmail.com)
The scientist who arranged the elements into triads was Dobereiner.
The two most common triads are the Major and the minor triad. The other two types of triads are diminished and augmented triads.
Dobereiner's triads: the first attempt to classify chemical elements.
T tubules and sarcoplasmic reticulum (SR) form triads.
a note
Johann Wolfgang Dobereiner,a German chemist arranged atom in the form of triads in 1817.
Polychord
The Law of Triads was written by Johann Dobereiner in 1817. He was a German chemist, and the development of the Periodic Table began with him.
Dobereiner's Triads refers to an early arrangement of elements in which J.W. Dobereiner arranged them by their atomic mass in groups of three.
Döbereiner (working after 1815) was the first which found some rules for the rational arrangement of chemical elements. He proposed in 1829 the law of triads - only five triads were discovered.
a three-note chord,
Triads literally means 'a group of three'. Could be the grouping of CRT phosphor dots, of a book series, and so on. It is an ancient and obvious concept.
When two triads are played at the exact same time, it is commonly called a Polychord. Poly typically means three.

There is no record of Daniil being part of the Russian mafia or Triads, that does not mean he does or does not have involvement. He is not currently on any lists as a member of that faction.
Dobereiner was responsible for grouping element into triads. He grouped 3 element with same properties together.

In a major scale there are three minor triads. In every major scale the ii chord, iii chord, and vi chord are always minor.
These triads are: Li-Na-K, Ca-Sr-Ba, Cl-Br-I, S-Se-Te.
Dobereiner gave triads for few elements. It could not be applied to other elements.So it was not considered further.
