Question

One success of Johann Döbereiner's law of triads was that it organized most of the known elements into three-element groups based on similarities in their properties. (Points : 2)

True
False

Answer 1

True.

Step-by-step explanation:

In 1824, the German chemist Johann Dobereiner, when analyzing the chemical elements calcium (Ca), strontium (Sr) and barium (Ba), noticed a simple relationship between their atomic masses: the mass of the strontium atom was very close to mass average of the other two elements. This observation was named the Triads of Chemical Elements and thus was born the law of the triads of Johann Döbereiner.

This law argued that elements with similar properties, ie, which reacted similarly with other elements, were organized in groups of three.

Answer 2

that statement is true

it was easy to organize 'all' the elements in a group of threes because back then they only knew about 15 - 20 elements

hope this helps
