What subatomic particle has a charge of -1?
The electron is a subatomic particle that has a charge of -1.
Which subatomic particle did James chadwick discover?
James Chadwick discovered the neutron, a subatomic particle that is found in the nucleus of an atom. He made this discovery in 1932, building upon the work of previous scientists in the field of atomic theory.
What was the experimental evidence that Thomson had discovered the existence of a subatomic particle when working with cathode rays?
Thomson discovered the electron and proved that it existed without ever being able to see or isolate one. Electrons were the first subatomic particles to be discovered, the first particle of matter identified that was smaller than an atom. This discovery also finally provided some physical proof of, and description of, the basic unit that carried electricity. Thomson attached thin metal plates inside his cathode ray tube to a battery and showed that an electrical field could also deflect cathode rays.
Identify the smallest particle of matter how were they discovered?
The smallest particle of matter is an atom, which was discovered in the early 20th century through experiments such as the gold foil experiment by Ernest Rutherford. It was found that atoms are made up of even smaller particles called protons, neutrons, and electrons.
Is an electron a sub atomic particle in the nucleus that is attracted to electrons?
no. ions are made of relatively whole atoms (plus or minus a few electrons)
When was the first subatomic particle discovered?
This particle was the electron.
What was the first subatomic particle discovered?
Subatomic particles are particles that are smaller than atoms. There are two different types of subatomic particles: elementary particles and composite particles. The first subatomic particle that was discovered was the electron. It was first theorized to exist by G. Johnstone Stoney in 1874 and was confirmed to exist in 1897 by J.J. Thomson.
What was the first subatomic particle created?
This particle was the electron discovered in 1897 by Joseph John Thomson.

Who discovered the negatively charged subatomic particle?
The neutron was discovered by James Chadwick in 1932.
Which particle did j.j. Thomson discover?
