Polonium 212 has 84 protons and 128 neutrons. An alpha particle is 2 protons and 2 neutrons, so the daughter nucleus will have 82 protons and 126 neutrons, making it lead 208.
This isotope is lead-208 (Pb-208).
All isotopes of polonium can undergo alpha decay, a small number of isotopes can also undergo beta decay, K capture decay, or gamma decay.
232U alpha decays to 228Th. Thorium-228 is the daughter product of the alpha decay of uranium-232.
By alpha decay polonium-214 is transformed in lead-210. Po-214--------------alpha--------------Pb-210
The isotope radon-198 will alpha decay to polonium-194 as shown here: 86198Rn => 24He + 84194Po The radon is shown on the left, and the alpha particle, which is a helium nucleus, is shown of the right with the polonium.
Each isotope has a specific radioactive decay.
The decay of 212Po84 goes like that:212Po84 ----- 4a2 + 208Pb82The lead isotope that forms, 208, is stable.
All isotopes of polonium can undergo alpha decay, a small number of isotopes can also undergo beta decay, K capture decay, or gamma decay.
The reaction is:Po-216----------------alpha particle-----------------Pb-212
After the alpha decay of polonium-212, there is lead-208 212/84 Po --------> 208/82 Pb + 4/2 He Lead 208
232U alpha decays to 228Th. Thorium-228 is the daughter product of the alpha decay of uranium-232.
By alpha decay polonium-214 is transformed in lead-210. Po-214--------------alpha--------------Pb-210
The isotope radon-198 will alpha decay to polonium-194 as shown here: 86198Rn => 24He + 84194Po The radon is shown on the left, and the alpha particle, which is a helium nucleus, is shown of the right with the polonium.
Each isotope has a specific radioactive decay.
Radon-222 undergoes alpha decay to produce polonium-218as a daughter.
Polonium-218-------------alpha---------------Lead-214
It is alpha decay. In the process, an alpha particle(He2+) is released. So, it is called alpha decay.
The equation for the alpha decay of 210Po is: 84210Po --> 82206Pb + 24He representing the alpha particle as a helium nucleus. 206Pb, the daughter atom, is stable.
