singleproton
A single proton is a fundamental subatomic particle carrying a positive electric charge. It is a baryon, meaning it is composed of three quarks, specifically two up quarks and one down quark. Protons are a key component of the atomic nucleus, along with neutrons. The number of protons in an atom's nucleus, known as the atomic number, defines the element. For example, an atom with one proton is hydrogen, while an atom with six protons is carbon.
Protons are remarkably stable particles. Their mass is approximately 938.272 MeV/c², which is about 1836 times
