why discovery of elements became easier after the Mendeleev classification of elements explain
Answers
Answer:
In the mid-1700s, chemists began actively identifying elements, which are substances made up of just one kind of atom. But a century later, they still used a variety of symbols and acronyms to represent the different materials — there just wasn’t a common lexicon. In 1869, the Russian chemist Dmitri Mendeleev came to prominence with his tabular diagram of known elements. This basic ingredient list, of which all matter exists, became known as the periodic table. Here’s what’s especially amazing: Mendeleev’s chart allotted spaces for elements that were yet to be discovered. For some of these missing pieces, he predicted what their atomic masses and other chemical properties would be. When scientists later discovered the elements Mendeleev expected, the world got a glimpse of the brilliance behind the periodic table.
Answer:
When Mendeleev arranged the elements in order of increasing atomic mass, the properties where repeated. ... Mendeleev went even further. He corrected the known atomic masses of some elements and he used the patterns in his table to predict the properties of the elements he thought must exist but had yet to be discovered.
Explanation:
He had noticed a relation between atomic masses of elements and their chemical and also physical properties. He observed that there was a periodic re-occurrence of elements with similar properties. So Mendeleev arranged these elements in a grid, that we today know as a periodic table. Mendeleev stated that “properties of elements are the periodic function of their atomic masses” and this came to be known as Periodic Law.
