somebody did something rite :P
Only by experiments during long periods (exception are probable quarks and gluons proposed by a theory but not clearly identified by experiments).

What are the properties of particles?
The atom is the smallest part of matter that represents a particular element. For quite a while, the atom was thought to be the smallest part of matter that could exist. But in the latter part of the 19th century and early part of the 20th, scientists discovered that atoms are composed of certain subatomic particles and that, no matter what the element, the same subatomic particles make up the atom. The number of the various subatomic particles is the only thing that varies. Scientists now recognize that there are many subatomic particles (this really makes physicists salivate). But in order to be successful in chemistry, you really only need to be concerned with the three major subatomic particles: Protons Neutrons Electrons
What are the Subatomic particles with no charges?
Subatomic particles with no charges are neutrons
Subatomic particles bigger than molecles?
subatomic particles make up the molecule
Who is model of the atom has no subatomic particles?
Both Democritus' and John Dalton's atomic models had no subatomic particles.
What are the Three basic subatomic particles?
The three sub-atomic particles are:# Proton # Electron # NeutronAtoms are made up of Electrons, Neutrons, and Protons. These subatomic particles are known to be made up of even smaller particles. Particle accelerators are being used today to discover more of these particles.
What observations led scientists to propose the existence of subatomic particles?
Atoms were found to be divisible after all . But scientists discovered that the atoms were made of smller perticles , called subatomic particles.
What is the smallest part of a comet?

Which two scientists discovered the subatomic particles that make up the nucleus?
Chadwick and Rutherford

What are the Subatomic particles with no charges?
Subatomic particles with no charges are neutrons
What are the subatomic particles with no mass called?
All subatomic particles have mass.
Why are scientists concerned about subatomic particles?
For the particles in the atom: Neutron: James Chadwick, 1932 Electron: J. J. Thomson, 1897 Proton: Ernest Rutherford, 1919
What subatomic particle did the gold foil experiment discover?
Rutherford's gold foil experiment did not discover the existence of any subatomic particles, but it did show the existence of a small, tightly packed, positively charged nucleus and thus led to the discovery of protons.
What is in between subatomic particles?
Subatomic particles are: neutron, proton, electron.
Are photos made of subatomic particles?
Everything is made of subatomic particles.
What are properties that vary among subatomic particles?
The atom is the smallest part of matter that represents a particular element. For quite a while, the atom was thought to be the smallest part of matter that could exist. But in the latter part of the 19th century and early part of the 20th, scientists discovered that atoms are composed of certain subatomic particles and that, no matter what the element, the same subatomic particles make up the atom.

What is A particle not made up of other particles?
subatomic particleIn physics or chemistry, subatomic particles are the small particles composing nucleons and atoms. There are two types of subatomic particles: elementary particles, which are not made of other particles, and composite particles.
