Question

HOW DID MENDELEEV'S PERIODIC TABLE HELP IN THE DISCOVERY OF NEW ELEMENTS.

Answer 1

He was also able to work out the atomic mass of the missing elements, and so predict their properties. And when they were discovered, Mendeleev turned out to be right. For example, he predicted the properties of an undiscovered element that should fit below aluminum in his table.

Hope this will help you ☺☺

Answer 2

Answer:

mark me as brainliest nd thank me if the answer is useful.

Explanation:

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. He left blank spaces in his chart as placeholders to represent those unknown elements.
