Beta minus decay emits a positron so a proton is changed to a neutron in this process. This means that caesium 137 decays to Xenon 137
Atoms can typically endure for billions of years before undergoing decay or transformation.
The atomic number of an atom undergoing alpha decay decreases by 2. Not asked, but answered for completeness, the atomic mass number decreases by 4.
Oxygen-17 would become fluorine-17 after undergoing alpha decay, and then it would decay into oxygen-17 again after undergoing beta decay. Alpha decay involves emitting an alpha particle comprising two protons and two neutrons, while beta decay involves either emitting an electron (beta minus decay) or a positron (beta plus decay) to change the nucleus.
alpha decay - fully ionized helium nucleibeta decay - electrons or positrons, and electron neutrinosgamma decay - very high energy photons
Lead-209 undergoes beta- decay to become Bismuth-209 82209Pb --> 83209Bi + -10e + v-e emitting an electron and an electron antineutrino.
The nuclear equation for the decay of Po-210 undergoing 2 alpha decays followed by a beta decay and another alpha decay is: Po-210 -> Pb-206 + 4 He-4 + 2 e-1 + 2 v This equation represents the series of decays that result in the transformation of Po-210 into Pb-206, with the emission of two helium nuclei (alpha particles), two electrons, and two neutrinos.
Particles or electromagnetic waves
No, in alpha decay the atomic number of the daughter nucleus is decreased by 2 and the mass number is decreased by 4 compared to the isotope undergoing decay. This is because an alpha particle (helium nucleus) is emitted during alpha decay, resulting in a new daughter nucleus with a lower atomic and mass number.
If the graph, from left to right, is going upwards, with an increasing gradient (slope) then it is undergoing growth. If it is going downwards, with a decreasing gradient (slope) then it is undergoing decay.
alpha
The negative charged particle emitted during radioactive decay is called a beta particle. It is essentially an electron that is released from the nucleus of the atom undergoing decay in order to conserve charge. Beta decay occurs when a neutron in the nucleus is transformed into a proton, releasing a beta particle and an antineutrino.
The abundance of an isotope is strongly correlated with its stability. Isotopes with longer half-lives are more abundant because they persist for a longer period of time without undergoing radioactive decay.
