What is the Contribution of ernest Rutherford to science?

Answer 1

Ernest Rutherford contributed to the understanding of the atom. He used J.J Thomsons model and conducted a expirements in which he shot positively charged particles throught a thin gold foil. He predicted that all the high speed particles would pass straight through the foil without being affected by the gold atoms. Instead, the results showed that while most particles did behave as predicted, some were greatly deflected.

Answer 2

Mr. Rutherford's single greatest contribution was the outcome of his "gold foil experiment." Do an internet search and you'll see several great animations. Basically it proved the basics of atomic structure: protons and neutrons are in the small, dense atomic nucleus, which accounts for nearly all the atom's mass. Electrons lie in a cloud of negative charge far outside this nucleus, and account for nearly all the atom's volume.

Answer 3

Without the knowlege of Rutherford we wouldn't have alpha or beta or gamma rays

Answer 4

the discovery of the nucleus
