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 However, the law of triads was later superseded by more accurate and comprehensive periodic table arrangements.

Which of these observations led to the law of triads?
The observation that groups of three elements had similar properties and atomic weights led to the development of the law of triads by Johann Dobereiner in early 19th century chemistry. This law suggested that elements could be grouped into sets of three with similar characteristics where the atomic weight of the middle element was roughly the average of the other two.
What quantity that measures how much a machine multiplies force or distance?
The quantity that measures how much a machine multiplies force or distance is called mechanical advantage. It is calculated by dividing the output force of the machine by the input force or by dividing the output distance by the input distance. An ideal machine would have a mechanical advantage greater than 1, indicating that it magnifies either force or distance.
What is advantage of dejure?
One advantage of de jure is that it ensures clear and formal legal recognition and protection of rights or status. It can provide a strong legal basis for individuals or entities to assert their rights or challenge decisions that are not in accordance with the established law. Additionally, de jure recognition tends to promote consistency and predictability in legal outcomes.
What is Gaussian Surface?
A Gaussian surface is an imaginary closed surface used in Gauss's law to calculate the electric field or flux through the surface. It is often chosen to simplify the calculation by taking advantage of the symmetry of the system.
How does mechanical advantage differ from ideal mechanical advantage?
Mechanical advantage is determined by physical measurement of the input and output forces and takes into account energy loss due to deflection, friction, and wear. The ideal mechanical advantage, meanwhile, is the mechanical advantage of a device with the assumption that its components do not flex, there is no friction, and there is no wear.

What are the merits and demerits of dobereiner law of triads?
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.
What Resulted from the first experimental effort that established the idea of group of elements?
The Law of triads
What was the exact date of johann dobereiner's discovery?
Johann Wolfgang Döbereiner discovered the concept of the law of triads in 1817.
What are dobereiner's triads defect?
the main defect of' dobereiner's triads is that he put the chemically dissimilar elements in the same triads (dahal.ramchandra@gmail.com)
What are the kinds of triads?
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.
What did Johann dobreiner do for the periodic table?
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
What are the two most common types of triad?
The two most common triads are the Major and the minor triad. The other two types of triads are diminished and augmented triads.
Who was Dobereiner?
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.
How was Döbereiner's concept of triads an important step in the developement of the periodic table?
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.
