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
When you combine neutrons and protons you get an atomic nucleus.
there are 66 protons & 97 neutrons
13 protons and 14 neutrons
Mass number is about the neutrons and protons. The total of neutrons and protons.
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.
Chemical reactions involve valence electrons and not protons.
radioactive decay
meson exchange between protons & neutrons.
Neutrons are completely separate from protons, so neutrons do not have any protons, and protons do not have any neutrons.
Transmutation always involves a change in the number of protons in the atom, which changes the atomic number and the element of the atom. It also involves at least some slight change in the mass of the atom (but not necessarily the mass number, which is the number of protons plus the number of neutrons, and not the same as the actual mass).
Protons and Neutrons.
The Nuclear Force is caused by the exchange of pions between the protons and the neutrons.
The "strong force," or sometimes called the "strong nuclear force." This is the exchange of gluons between the protons and neutrons.
The 46 = #Neutrons + #Protons and 22 = #Protons so... # Neutrons = 26
