Question

Hi


Explain Dobereneir's triad
..

Answer 1

Hola User ______________

Actually this the First law from the chapter....Classification of the Elements....
Basically the Dobereneir's law of triad was only successful for some of the triad of the Elements only......

It stated that ...when the three Elements were arranged in the fashion of increasing Atomic masses ..then in a triad the Arithmetic mean of the masses of the two elements was approximately equal to the atomic mass of the middle element......,
ONE OF THE EXAMPLE FOR THIS LAW IS THE
Lithium , Sodium and Potassium triad....

Hope this helps u...........☺

Answer 2

definition:-
the dobereneir"s traids is states that " if we arrange all the elements according to their increasing atomic masses order, then the group of three elements with similiar chemical properties are found which is called traids.And the arithmetic mean {AVERAGE} of atomic mases of first and third element is equal to the atomic mass of second element.

EXAMPLE:-let traid one:-

element         atomic mass
lithium                     7
sodium                    23
potassium              39
       VERIFICATION:-     ===  7+39/2=26{atomic mass of middle element}
