Who is model of the atom has no subatomic particles?
The model of the atom with no subatomic particles is the Dalton model, proposed by John Dalton in the early 19th century. In this model, atoms were considered indivisible and the smallest building blocks of matter. Subatomic particles like protons, neutrons, and electrons were not discovered until much later.
Subatomic particles bigger than molecles?
Subatomic particles are smaller than molecules and are the building blocks of atoms. Protons, neutrons, and electrons are examples of subatomic particles found in atoms. There are no known subatomic particles that are bigger than molecules.
What are the Subatomic particles with no charges?
Subatomic particles with no charges are neutrons
How many subatomic particles does chlorine have?
Chlorine has 18 subatomic particles, which consist of 17 protons, 18 neutrons, and 17 electrons.
Who is discovered the nucleus and its subatomic particles?
The nucleus of an atom was discovered by Ernest Rutherford in 1911 through his gold foil experiment. Subatomic particles within the nucleus, such as protons and neutrons, were later identified by James Chadwick in 1932.
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 last subatomic particles?
If you think to particles in the atom: the neutron was discovered in 1932 by James Chadwick.
Who discovered subatomic particles with no charge?
The neutron was discovered in 1932 by James Chadwick.
Who discovered the subatomic particles of proton?
The proton was discovered by Ernest Rutherford in 1917-1919.
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 scientist discovered positively charged subatomic particles?
Ernest Rutherford in 1919.
How many subatomic particles have been discovered to date?
more than 400
Who discovered subatomic particles during work with cathode tubes?
j.j. Thompson
How subatomic particles were discovered in the 1900s?
Before 1900 only the electron was known.
Who discovered the subatomic particle?
The concept of subatomic particles emerged in the late 19th and early 20th centuries through the research of scientists such as J.J. Thomson, Ernest Rutherford, and Niels Bohr. The discovery of specific subatomic particles like the electron, proton, and neutron can be attributed to a combination of experimental observations and theoretical advancements by multiple scientists over time.
