Web1.Dobereiner’s triads was clearly an intuitive observation. It was not based on experimentation like the Lother Meyer curve or Moseley’s law, nor was it based on rigorous observations like that of Mendeleev. So, clearly, only a handful of triads could actually be reported. This itself caused the theory to be rejected. 2. WebAccording to Dobereiner’s laws of triads, when some elements of chemical groups form in order to increase atomic masses, triads or groups of three elements have similar chemical properties to obtain. The atomic mass of the middle element of the triads can be equal to the arithmetic mean of the atomic masses of the other two elements.

WebTriads There are four possible ways to combine major and minor 3 rds to produce a tertian triad. Triads: Members of the Chord The notes (members) of the chords are given names. Seventh Chords If we extend a tertian triad by adding another 3 rd on top of the 5 th of the triad, the result is a four-note chord called a seventh chord.

When these elements were arranged in increasing order of their atomic masses, they generally occurred in groups of three. These groups were called triads.

Johann Wolfgang Döbereiner was born in Jena (Germany) on December 13, 1780 and died on March 24, 1849, at the age of 69. His father, Johann Adam Döbereiner, worked as a coachman, which meant that Döbereiner did not have many training opportunities within the formal system.
