Who discovered the last subatomic particles?
If you think to particles in the atom: the neutron was discovered in 1932 by James Chadwick.
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.
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.
Are subatomic particles found inside atoms?
Yes, atoms contain subatomic particles.
Positrons mesons neutrinos and others are usually called?
subatomic particles :)
How many subatomic particles were discovered in the 1900s?
Three subatomic particles were discovered in the 1900s: the neutron in 1932, the positron in 1932, and the neutrino in 1956.
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.

Who discovered the subatomic particles of proton?
The proton was discovered by Ernest Rutherford in 1917-1919.
What makes up the subatomic particles?
Atoms are made up of protons, neutrons and electrons. However, each of these subatomic particles is made up of smaller subatomic particles such as quarks.
