More evidence began to accumulate, more elements were discovered, and it even became possible to calculate the number of atoms in a particular sample. The first step, along this direction, was made by Amedeo Avogadro (1776–1856).
WebJan 25, 2024 · Ans: The structure of an atom was proposed by John Dalton in \ (1803,\) who developed a more scientific definition of an atom. He considered atoms as small spheres that are indivisible and that atoms of an element are identical to each other. He came up with a theory popularly known as “Dalton’s Atomic Theory”. Q.2.
