Who discovered that electric charges are positive or negative?
Robert Millikan discovered the electron's charge using the oil drip experiment. Eugene Goldstein discovered positive particles with the anode/cathode ray tube. James Chadwick discovered the neutral particle with the beryllium and paraffin wax experiment.
Who discovered that atoms contain subatomic particles?
J.J. Thomson discovered the first subatomic particle, the electron, in the late 19th century through his experiments with cathode rays. This discovery led to the understanding that atoms contain subatomic particles.
Who discover anode rays?
Anode rays were discovered by German physicist Eugen Goldstein in 1886 while studying the behavior of cathode rays in a partially evacuated tube. They are positively charged particles that travel in the opposite direction of cathode rays when a high voltage is applied across the electrodes in the tube.
Who was the inventor of proton - Rutherford or Goldstein?
The proton was first discovered by Ernest Rutherford in 1917 during his gold foil experiment. Wilhelm Wien and Eugen Goldstein contributed to the understanding of the proton, but Rutherford is credited with its discovery.
Who and when discovered the electron scanning microscope?
Charles Oatley in 1952 discovered the electron scanning microscope, but Max Knott created the first prototype of the SEM in 1935.
What is the contribution of Eugene Goldstein in chemistry?
Eugen Goldstein was a German physist and was one of the first people to investigate x-rays.Goldstein also discovered Cathode Rays.
Who discover that What is inside the atom?
Sir J.J Thomson first discovered that atoms had a negatively charged particle called an "ELECTRON". Afterwards , Goldstein discovered "PROTONS", the positively charged particles.
What year did eugen goldstein create an atomic model?
Eugen Goldstein did not create an atomic model. He is known for discovering the proton in 1886. The development of atomic models came later, with contributions from scientists like J.J. Thomson, Ernest Rutherford, Niels Bohr, and others.
E. Goldstein discovered which subatomic particle?
Eugen Goldstein proposed the expression cathode rays(but he was not the discoverer) and discovered the so-called in the era canal rays.
Who discovered the positively charged particle in the atomproton?

Who discovered evidence of positively charged particle?
It's goldstein.
When was the element germanium discovered?
Germanium was discovered in 1886 by Clemens A. Winkler.
