Subatomic Particle Properties
Subatomic particles are the fundamental building blocks of matter. They are extremely small, with masses that are a tiny fraction of an atom’s mass. Subatomic particles have three basic properties: charge, mass, and spin.
Charge refers to the electrical charge of a particle. Protons have a positive charge, electrons have a negative charge, and neutrons have no charge. Mass refers to the amount of matter in a particle. Protons and neutrons have approximately the same mass, which is about 1 atomic mass unit (amu).
Electrons have a much smaller mass, which is about 1/1836 amu.
Spin refers to the intrinsic angular momentum of a particle. Protons and neutrons have a spin of 1/2, while electrons have a spin of 1/2. Spin is a quantum property that can only take on certain discrete values.
Summary of Key Properties of Protons, Neutrons, and Electrons
| Property | Proton | Neutron | Electron |
|---|---|---|---|
| Charge | +1e | 0 | -1e |
| Mass | 1 amu | 1 amu | 1/1836 amu |
| Spin | 1/2 | 1/2 | 1/2 |
Subatomic Particle Interactions
Subatomic particles interact with each other through three fundamental forces: the strong force, the weak force, and the electromagnetic force.
The strong force is the strongest of the three forces. It is responsible for holding the protons and neutrons together in the nucleus of an atom. The strong force is only effective over very short distances, about the size of an atomic nucleus.
The weak force is responsible for certain types of radioactive decay. It is also involved in the interactions between neutrinos and other particles. The weak force is much weaker than the strong force, but it has a longer range.
The electromagnetic force is responsible for the interactions between charged particles. It is the force that causes electrons to orbit the nucleus of an atom. The electromagnetic force is much weaker than the strong force, but it has a much longer range.
