The average of two atomic weights for a group of three elements equaled the atomic weight of the third.
The law of triads helped in identifying patterns and relationships among elements, leading to the development of the periodic table. It also played a key role in the early classification of elements based on their atomic masses and properties. However, the law of triads was later superseded by more accurate and comprehensive periodic table arrangements.
A brief statement summarizing many observations of a physical phenomenon is called scientific law. The density of an object is the ratio of its mass to volume.
The relationship is, in order to become a scientific law, you have to have many observations by many different people. If you want to prove it is not a theory, you have to observe it.
A scientific law is backed up by extensive empirical evidence and repeated observation that consistently supports the relationship or pattern described by the law. Laws are considered fundamental principles of nature that have withstood rigorous testing and have not been found to be contradicted by any observations or experiments.
A scientific law is a statement describing observable phenomena. Laws are based on repeated observations and experimentation, so they are not typically "broken." If an event seems to contradict a scientific law, it may indicate a limitation in our understanding or a need to revise the law.

The merit of Dobereiner's Law of Triads is that it recognized patterns in chemical properties of certain elements and grouped them together based on similarities. However, a major demerit is that it was limited in its application and only applied to a few elements, making it less useful as more elements were discovered that did not fit into triads.
The Law of triads
Johann Wolfgang Döbereiner discovered the concept of the law of triads in 1817.
Law . (: law!!;)
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.
Is a scientific law an explaination of thing or events based on observations of an explariment
the value of scientific law is the set of observations...
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
