The particle theory provides a model to help us understand the differences between fluids and solids.
An atom.
that would be an electron
The Particle Theory of Matter states that all matter is made up of tiny, indivisible particles called atoms or molecules. These particles are in constant motion and have spaces between them. Changes in matter involve rearrangement or separation of these particles rather than their creation or destruction.
A neutron, ie. neutral, Where a proton would be positive, and an electron, negative.
Protons and neutrons contain quarks and gluons; electron is a fundamental paticle.
The smallest particles on earth are called quarks. Quarks are the fundamental particles that make neutrons and protons in atoms.
the paticle that was hard to detect was neutrons because it had no electrical charge.
