Who is known as Father of Periodic Table? Which important property did he use to classify the
elements in his periodic table?
Answered by admin @
Answer:
Dimitri Mendeleev
In 1869 Russian chemist Dimitri Mendeleev started the development of the periodic table, arranging chemical elements by atomic mass. He predicted the discovery of other elements, and left spaces open in his periodic table for them. In 1886 French physicist Antoine Bequerel first discovered radioactivity.
Explanation:
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.
Based on other elements in the same group he predicted the existence of eka-aluminum, eka-boron, and eka-silicon, later to be named gallium (Ga), scandium (Sc), and germanium (Ge). Mendeleev predicted the atomic mass of each element along with compounds they each should form.
