Johann Dobereiner
- noticed that the atomic weight of strontium fell midway between the weights of calcium and barium, elements possessing similar chemical properties.
In 1829, after discovering the halogen triad (composed of chlorine, bromine, and iodine) and the alkali metal triad of (lithium, sodium and potassium)
***he proposed that nature contained triads of elements the middle element had properties that were an average of the other two members when ordered by the atomic weight (the Law of Triads)
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.
Triads were developed by Giovanni Battista Mancini, an Italian singing teacher and voice instructor in the 18th century. Mancini's work in music theory and vocal pedagogy contributed to the understanding and application of triads in Western music.
johann dobereiner had contributed towards the base of the periodic table and discovered that the elements shared similiar properties because there always was three elementzs in three groups that he later refered to as Triads.
Dobereiner was a German scientist who was one of the first men to discover a pattern in elements ultimately leading to the periodic table you use in science today. Dobereiner saw a pattern in chemical properties of elements, he saw these patterns in threes. These groups are called Triads. Later he found physical property patterns as well.Hope this will help you.
the main defect of' dobereiner's triads is that he put the chemically dissimilar elements in the same triads (dahal.ramchandra@gmail.com)
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.
The major triads are typically named based on their root notes, which include C major, D major, E major, F major, G major, A major, and B major. Each triad consists of three notes: the root, the major third, and the perfect fifth. In addition to these, there are minor triads, diminished triads, and augmented triads, which also have their own names based on the root notes.

a three-note chord,
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).
