Respuesta :
a) Neutrons or protons are the particles that have an impact on the stability of the atom.
b) Electrons are the particles that have no impact on the stability of the atom.
When an element's atoms have excess neutrons or protons, the extra energy produced in the nucleus causes the atom to lose its equilibrium or become unstable.
Whether or not an atom's outermost shell is filled with electrons determines how stable the atom is. The molecule is stable if the outer layer is full. To attain stability, vacant outer shell atoms often form chemical interactions with other atoms.
Radioactivity is the capacity of some unstable atoms to spontaneously release nuclear radiation, often in the form of alpha and beta particles associated with gamma rays. The nucleus of an atom might become unstable if there are too many neutrons or protons present.
By ejecting other particles, such as neutrons and protons, or by emitting radiation in a variety of ways, a radioactive atom will attempt to become stable. Thus, the atom's electrons are the only internal particle that has no impact on the atom's stability.
