Question

who is known as father of periodic
Table ? which important property did
he use to classify the element in
his periodic table?​

Answer 1

Answer:

mendeleev

Explanation:

The important property that Mendeleev used for the classification of elements was atomic weight. He arranged all known elements in the form of periodic table. Some of the elements did not fit very well if the order of atomic weight was strictly followed. For these elements, he ignored the order of atomic weight (as atomic weight measurements can be incorrect) and placed the elements with similar properties together. Thus, iodine having lower atomic weight than tellurium (of group VI) was placed in group VII along with fluorine, chlorine and bromine due to similar properties and left some gaps for undiscovered elements.

Answer 2

Answer:

Mendeleev

Mendeleev used atomic weight as the basis of classification of elements in the periodic table. He arranged the then known elements in order of increasing atomic weights grouping together elements with similar properties.
