An alpha particle has a mass of 4 and a charge of +2, therefore it must be a He-4 nucleus. (There is such a thing as He-3 that can be formed in nuclear reactions, but all natural alpha particles are He-4 nuclei.)
Now we know that the product nucleus must be Z (226-4), where Z is what we're looking for. He is the second element, thus it's atomic number is two. That means that it has two protons. Since the Ra-226 nucleus has lost two protons when it decays, Z has to be the element with an atomic number two less than Ra. The atomic number of Ra is 88, and the element with atomic number 86 is radon (Rn). We already determined that the Atomic Mass is 222 so that the answer is Rn-222.

What is the equation for alpha decay of Thorium?
232Th --> 228Ra + 4He 228Ra --> 228Ac + e- 228Ac --> 228Th + e- 228Th --> 224Ra + 4He 224Ra --> 220Rn + 4He 220Rn --> 216Po + 4He 216Po --> 212Pb + 4He 212Pb --> 212Bi + e- 212Bi --> 208Tl + 4He, 212Po + e- 208Tl --> 208Pb + e- 212Po --> 208Pb + 4He 208Pb, stable Other isotopes of Thorium undergo beta decay, but they are not naturally occurring.
To what does plutonium-239 decay when it loses an alpha particle?
Yes, plutonium-239 emits alpha particles by decay.
In alpha and beta decay the parent elements is always a different element from the daughter element?
true
What is the product of radioactive decay called?
Product of radioactive decay 42He is an alpha particle
Is alpha decay the same as alpha radiation?
No. Decay is the process, radiation is the product.
