Outside of a particle accelerator they aren't. It is a nuclear reaction although an actual exchange of protons would be very unlikely (depending on what you mean by "exchange").
protons and neutrons
there are 66 protons & 97 neutrons
When you combine neutrons and protons you get an atomic nucleus.
Mass number is about the neutrons and protons. The total of neutrons and protons.
13 protons and 14 neutrons
It involves the particles of the nucleus (protons and neutrons), not the electrons.
Protons and Neutrons in atomb bombs are found in the nuclear fission reaction.
Nuclear decay involves the contents of the atomic nucleus, the protons and neutrons. Chemical reactions involve the electrons.
radioactive decay
meson exchange between protons & neutrons.
The nuclear force, also known as the strong nuclear force, is caused by the exchange of particles called gluons between quarks inside protons and neutrons. This force is responsible for binding protons and neutrons together in the atomic nucleus.
Neutrons are completely separate from protons, so neutrons do not have any protons, and protons do not have any neutrons.
The "strong force," or sometimes called the "strong nuclear force." This is the exchange of gluons between the protons and neutrons.
Mesons hold protons and neutrons together by mediating the strong nuclear force between them. This force is carried by the exchange of mesons between quarks inside the protons and neutrons. The strong nuclear force is responsible for binding protons and neutrons together in the atomic nucleus.
None -- all protons are protons, which are different from neutrons.
14 protons and 14 neutrons
Protons are positively charged and neutrons are neutral.
