proton 官网

Protons are subatomic particles that hold immense power within the world of particle physics. Found within the nucleus of an atom, protons carry a positive charge that helps to hold the atom together. Along with neutrons, protons make up the majority of an atom's mass. The number of protons in an atom determines its atomic number, which in turn dictates the element it represents. For example, an atom with one proton is hydrogen, while an atom with 79 protons is gold. In addition to their role in defining elements, protons also play a significant role in nuclear reactions. In nuclear fusion, protons combine to form larger nuclei, releasing enormous amounts of energy in the process. This phenomenon is harnessed in nuclear power plants to produce electricity. Overall, protons are essential building blocks of matter and hold incredible power within the world of particle physics.
