proton 官网

Protons are subatomic particles found within the nucleus of atoms. They carry a positive electrical charge and are one of the building blocks of matter. Along with neutrons, protons make up the nucleus of an atom, while electrons orbit around the nucleus. The number of protons in an atom determines its atomic number and defines the element. For example, hydrogen has one proton, carbon has six, and gold has 79. This unique property allows scientists to classify and identify different elements based on their proton count. In particle physics, protons are also key players in particle accelerators, where they are accelerated to near-light speed and collided with other particles. These high-energy collisions provide valuable insights into the fundamental forces and particles that make up the universe. Overall, protons are essential components of the physical world, from the smallest atoms to the vast reaches of the cosmos. Their positive charge and unique properties make them fascinating subjects for scientific study.
