It is alpha decay.
In the process, an alpha particle(He2+) is released.
So, it is called alpha decay.
bismuth 210 decays by beta decay to polonium 210 that decays by alpha decay to lead 206
Polonium-210 decay to lead-206.
Polonium-210 lose an alpha particle and become lead-206.
By alpha decay polonium-214 is transformed in lead-210. Po-214--------------alpha--------------Pb-210
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.
bismuth 210 decays by beta decay to polonium 210 that decays by alpha decay to lead 206
Polonium-210 decay to lead-206.
Polonium-218 decay to lead-214.
Polonium-212 loses 2 protons and 2 neutrons when it decays to lead-208. These 2 protons and 2 neutrons are lost as a single Helium nucleus. In other words, it is an alpha decay.
Polonium-210 lose an alpha particle and become lead-206.
After the alpha decay of polonium-212, there is lead-208 212/84 Po --------> 208/82 Pb + 4/2 He Lead 208
Lead-208 is formed by alpha decay (emission of alpha particles) from polonium-212.
Polonium-218-------------alpha---------------Lead-214
By alpha decay polonium-214 is transformed in lead-210. Po-214--------------alpha--------------Pb-210
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.
No, after the alpha decay of polonium lead isotopes were obtained.
Radium itself continues to decay into radon, bismuth, polonium, lead, or thallium.
