Which scientist used a cathode ray tube to discover negatively charged subatomic particles?
The scientist who used a cathode ray tube to discover negatively charged subatomic particles was J.J. Thomson.
What subatomic particles are used to calculate the mass of an atom?
Protons and neutrons are the subatomic particles used to calculate the mass of an atom. Electrons are much lighter and are not typically included when calculating the mass of an atom.
What is Thompson's cathode ray?
Thompson's cathode ray refers to the experiment conducted by J.J. Thomson in the late 19th century where he discovered the existence of electrons. By observing the behavior of cathode rays in a vacuum tube, Thomson was able to determine the charge-to-mass ratio of the electron. This experiment was critical in shaping our understanding of atomic structure and the existence of subatomic particles.
What are the Three basic subatomic particles?
The three sub-atomic particles are:# Proton # Electron # NeutronAtoms are made up of Electrons, Neutrons, and Protons. These subatomic particles are known to be made up of even smaller particles. Particle accelerators are being used today to discover more of these particles.
What experiment convinced Ernest Rutherford thet atom has a small positively charged nucleus?
The gold foil experiment convinced Ernest Rutherford that the atom has a small positively charged nucleus. In this experiment, alpha particles were shot at a thin gold foil. The fact that some of the alpha particles were deflected and even bounced back led Rutherford to conclude that atoms have a small, dense, positively charged nucleus.
