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.
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.
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.
Dobereiner classified elements into groups of three. He introduced law of triads according to this law every element which comes in the middle of such a group has atomic mass equal to average of the atomic masses of first and third element. for example Lithium(Li) 7 Sodium(Na) 21 Potassium(K) 39
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.

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.
Antoine Lavoisier and Johann Wolfgang Döbereiner made contributions to the development of the periodic table before Mendeleev and Meyer. Lavoisier proposed a classification system based on properties of elements, and Döbereiner developed the concept of triads, which grouped elements with similar properties.
