Characteristics of doberbeiner's traids

Answer 1

$\huge\mathscr\red{Hi\: Dear}$

→According to Dobereiner, all elements occurred in groups of three, when arranged in increasing order of atomic masses. He referred to these groups as triads. In a traid the elements had similar chemical properties.

→The atomic mass of the middle element of a triad is the arithmetic mean of the atomic masses of the other two elements. Example: In the triad of lithium, sodium and potassium. The atomic mass of lithium is 7 and the atomic mass of potassium is 39. The average of masses of lithium and potassium gives atomic mass of sodium 23.

Hope it helps you❤

Answer 2

Hii here is your Answer friend..

Dobereiner's law of triads states that, the atomic mass of the middle element of a triad is the arithmetic mean of the atomic masses of the other two elements.

Example: In the triad of lithium, sodium and potassium. ...

The average of masses of lithium and potassium gives atomic mass of sodium 23.
