Polonium-210 lose an alpha particle and become lead-206.
The correct equation for the alpha decay of Polonium-214 is: 218/84Po -> 214/82Pb + 4/2He This shows the decay of Polonium-214 into Lead-214 and a Helium nucleus, where the atomic number and mass numbers are conserved.
Po-216- -----------------> Pb-212
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.

When bismuth-214 (Bi-214) undergoes radioactive decay, it primarily decays into polonium-214 (Po-214) through beta decay. Polonium-214 is also radioactive and further decays into lead-210 (Pb-210) via alpha decay. This sequence is part of the decay chain of uranium-238, where bismuth-214 is an intermediate product.
The correct equation for the alpha decay of Polonium-214 is: 218/84Po -> 214/82Pb + 4/2He This shows the decay of Polonium-214 into Lead-214 and a Helium nucleus, where the atomic number and mass numbers are conserved.
The daughter product that remains after the alpha decay of polonium-212 is lead-208. During alpha decay, polonium-212 loses an alpha particle, consisting of two protons and two neutrons, resulting in the transformation to lead-208.
The reaction is:Po-216----------------alpha particle-----------------Pb-212
The reaction is:Po-210------------alpha particle------------------Pb-206

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.
Lead 206 (Pb)
Lead, the isotope Pb 206.
Lead 206 (Pb)
All radioactive elements eventually decay to lead (Pb). There a numerous isotopes of lead and it is thought that all the lead(Pb) in the world is derived from decayed radioactive isotopes.
