In 1932, James Chadwick discovered the neutron. Neutrons help stabilize the protons in the atom's nucleus. Because the nucleus is so tightly packed together, the positively charged protons would tend to repel each other normally. Neutrons help to reduce the repulsion between protons and stabilize the atom's nucleus. Neutrons always reside in the nucleus of atoms and they are about the same size as protons. However, neutrons do not have any electrical charge; they are electrically neutral.

Who discovery neutrons?
The neutron was discovered by James Chadwick in 1932 through his experiments involving the bombardment of beryllium with alpha particles. Chadwick's discovery confirmed the existence of the neutron as a neutral subatomic particle with a mass similar to that of the proton.
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 chadwick experiment called?
James Chadwick shot alpha particles at a Beryllium target. Only the neutrons went through, not the protons. This allowed Chadwick to observe particles with no charge and find their mass. Thus, Chadwick discovered neutrons, and added them to Rutherford's model of the atom.
Who was the scientist that discovered neutrons?
James Chadwick is the scientist credited with the discovery of neutrons in 1932. He conducted experiments that led to the identification of the neutron as a fundamental particle found in the nucleus of atoms.
What is the subatomic particle with a negative charge?
The subatomic particle with a negative charge is the electron.
Who discovered the negatively charged subatomic particle?
The neutron was discovered by James Chadwick in 1932.
Who identified a neutral subatomic particle?
The neutron was discovered in 1932 by James Chadwick.
Which subatomic particle was discovered third?

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.
Which subatomic particle was not part of the Thompson model of the atom?
Neutron. We didn't know about them yet. Chadwick discovered them some time later.
Which subatomic particle's was not part of the Thompson model of the atom?
Neutron. We didn't know about them yet. Chadwick discovered them some time later.
What subatomic particle was discovered second?
The neutron was the second subatomic particle to be discovered, following the electron. It was discovered by James Chadwick in 1932 during experiments involving the bombardment of beryllium with alpha particles. The discovery of the neutron was crucial in our understanding of atomic structure and the development of nuclear physics.
Neutron was discovered by?
The neutron was discovered by Sir James Chadwick in 1932. Chadwick conducted experiments that provided evidence for the existence of a neutral subatomic particle within the atomic nucleus, which he named the neutron.
Who discovered subatomic particles with no charge?
The neutron was discovered in 1932 by James Chadwick.
Who discovery neutrons?
The neutron was discovered by James Chadwick in 1932 through his experiments involving the bombardment of beryllium with alpha particles. Chadwick's discovery confirmed the existence of the neutron as a neutral subatomic particle with a mass similar to that of the proton.
Which two scientists discovered the subatomic particles that make up the nucleus?
Ernest Rutherford and James Chadwick were the scientists who discovered the subatomic particles that make up the nucleus. Rutherford discovered the positively charged protons, while Chadwick discovered the uncharged neutrons.
