WebApr 2, 2024 · By 1900 the atomic theory was almost universally accepted by chemists. 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). WebApr 2, 2014 · Through further experimentation involving firing alpha particles at foil, Rutherford made the groundbreaking discovery that nearly the total mass of an atom is concentrated in a nucleus.
