Question

enlist the contribution of various scientist towards classification of elements?

Answer 1

Answer:

First of all, all elements are categorize into “metals and non-metals”. But many researchers and chemists have gone one step further to discover a more advanced classification scheme for the components.

Dobereiner’s Triads:

A German chemist and professor, Dobereiner to classify elements is usually regarded as the first effort to be recorded. He arranged similar properties of elements into one group called “traids”. But this method is not working properly.

Newland’s Law of Octaves:

John Newlands attempted to uniquely classify the elements. According to his, all elements are arranged in increasing order according to their molecular weight.

Mendeleev’s Periodic Table:

Now, this was the most effective Elements classification effort among all the previous efforts. Dmitri Mendeleev is actually known as "the father of the periodic table." We have our present periodic table because of his classification efforts.

Mendeleev said that "element characteristics are the ‘periodic function’ of their atomic masses," and this became known as Periodic Law. In this periodic table metals, nonmetals and metalloids are placed in the different groups.
