text: A proton by itself is thought to be stable, or at least its lifetime is too long to measure.
text: The spontaneous decay of free protons has never been observed, and protons are therefore considered stable particles according to the Standard Model.
text: Neutrons or protons bound in a nucleus can be stable or unstable, however, depending on the nuclide.
text: The proton is a stable particle, which means that it does not decay into other particles.
text: Proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1,836 times the mass of an electron.
text: And inside still other nuclides, both protons and neutrons are stable and do not change form.
text: Are protons fundamentally stable?
text: Neutrons or protons bound in a nucleus can be stable or unstable, however, depending on the nuclide.
text: Alas there is another problem at hand: in order for the proton to be stable we need to show that it can self-correct for any orbital imperfections and external disturbances.
text: If they are not free there is an important difference: protons are stable or highly stable while isolated neutrons decay by beta decay.

text: According to the Standard Model, protons, a type of baryon, are stable because baryon number (quark number) is conserved (under normal circumstances; see chiral anomaly for exception).
