the main defect of' dobereiner's triads is that he put the chemically dissimilar elements in the same triads (dahal.ramchandra@gmail.com)
No, Dobereiner's triads were a set of three elements with similar properties where the atomic mass of the middle element was approximately the average of the other two. Newlands' Octaves, on the other hand, arranged elements in rows of seven, where every eighth element showed similar properties. These two classification schemes were different from each other.
There are four types of triads: major, minor, augmented, and diminished. Major triads consist of a root, major third, and perfect fifth. Minor triads have a root, minor third, and perfect fifth. Augmented triads have a root, major third, and augmented fifth. Diminished triads have a root, minor third, and diminished fifth.
Triads are chords consisting of three notes: the root, the third, and the fifth. They are the fundamental building blocks of harmony in music. Triads can be major (happy-sounding), minor (sad-sounding), diminished (tense-sounding), or augmented (bright-sounding).
Dobereiner was responsible for grouping element into triads. He grouped 3 element with same properties together.
When two triads are played at the exact same time, it is commonly called a Polychord. Poly typically means three.

Some scientists supported Johann Dobereiner's theory of triads, which suggested that certain elements had similar properties and could be grouped together. However, the theory was later replaced by the modern periodic table developed by Dmitri Mendeleev.
Döbereiner's triads were rejected because they did not work for all elements and their properties as more elements were discovered. They were limited to grouping only a few elements with similar properties, and the periodic table provided a more comprehensive and accurate organization of elements based on atomic number and properties.
There are four types of triads: major, minor, augmented, and diminished. Major triads consist of a root, major third, and perfect fifth. Minor triads have a root, minor third, and perfect fifth. Augmented triads have a root, major third, and augmented fifth. Diminished triads have a root, minor third, and diminished fifth.
The two most common triads are the Major and the minor triad. The other two types of triads are diminished and augmented triads.
a note
A classical accompaniment style based on triads.
Johann Wolfgang Dobereiner,a German chemist arranged atom in the form of triads in 1817.
Polychord
Johann Dobereiner grouped elements with similar properties into triads. In these triads, he observed that the properties of the middle element were the average of the other two.
Dmitri Mendeleev arranged the elements into triads in the periodic table. Mendeleev noticed that elements with similar properties occurred at regular intervals when arranged by increasing atomic mass.
