What is the baryon number of all baryons?

Baryons are a class of subatomic particles that include protons and neutrons, which are the building blocks of atomic nuclei. The baryon number is a quantum number that represents the total number of baryons within a system.

Each baryon carries a baryon number of +1, while antibaryons, which are the antimatter counterparts of baryons, carry a baryon number of -1. In a system with baryons, the overall baryon number is simply the sum of the baryon numbers of all individual baryons present.

Since baryons such as protons and neutrons contribute positively to the baryon number, the baryon number of a collection of all baryons would be the total number of those baryons, resulting in a positive value. Therefore, when considering a collection of baryons, the baryon number would equal +1 for each baryon present, leading to a total baryon number that is typically positive as long as there are baryons in the system.

In summary, since the question concerns the baryon number associated specifically with baryons, each baryon contributes +1 to the total. Hence, the correct answer is that the baryon number of all baryons is +1.
