How subatomic particles were discovered in the 1900s?
Before 1900 only the electron was known.
Who discovered the subatomic particles of proton?
The proton was discovered by Ernest Rutherford in 1917-1919.

Describe the discovery that demonstrate for the first time that atoms are not the smallest particles of matter?
The discovery of the subatomic particles demonstrated for the first time that atoms are not the smallest particles of matter. Electron was the first subatomic particle discovered by J.J. Thomson.

How the 3 subatomic particles discover?
Subatomic particles were discovered through experiments involving the interaction of matter with various forms of radiation, such as beta particles, gamma rays, and alpha particles. Scientists like J.J. Thomson, Ernest Rutherford, and James Chadwick played integral roles in the discovery of electrons, protons, and neutrons, respectively. Their contributions to the field of atomic and nuclear physics helped unravel the nature of subatomic particles and their properties.
What are the 3 subatomic particles that make an atom?
These particles are: neutron, proton, electron.
What are the 3 subatomic particles in a atom?

Which of the 3 subatomic particles has negative charge?
This particle is the electron.
What is in between subatomic particles?
Subatomic particles are: neutron, proton, electron.
Did Robert millikan discover subatomic particles?
No, Robert Millikan did not discover subatomic particles; rather, he is best known for his work on the oil drop experiment, which measured the elementary charge of the electron. His experiments provided crucial evidence for the quantization of electric charge and helped confirm the existence of electrons as subatomic particles. Although he contributed significantly to the understanding of atomic structure, the discovery of subatomic particles like electrons was attributed to other scientists, such as J.J. Thomson.
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.
How many kinds of subatomic particles are there?
There are 3 kinds of Sub-Atomic particles. These are Proton, Electron, Neutron.
What is the smallest part of a comet?
The smallest part of a comet is likely the dust particles that make up its coma, which is the cloud of gas and dust that surrounds the comet's nucleus. These dust particles can be as small as a few micrometers in size.
Are photos made of subatomic particles?
No, photos are not made of subatomic particles. Photos are composed of photons, which are massless particles that carry electromagnetic force. Subatomic particles refer to particles like electrons, protons, and neutrons, which make up atoms.
