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 are the possible products of the alpha decay of uranium-238?
The possible products of the alpha decay of uranium-238 are thorium-234 and helium-4. During alpha decay, the uranium nucleus releases an alpha particle (helium nucleus) and transforms into thorium-234.
What is the product of radioactive decay symbolized by called?
A gamma wave...
What is the daughter product of uranium 238 by beta and gamma emission?
The decay product of uranium 238 by alpha disintegration (not beta or gamma) is thorium 234.
To what does plutonium-239 decay when it loses an alpha particle?
Yes, plutonium-239 emits alpha particles by decay.
Daughter product in part a decays by alpha emission?
Alpha decay is the emission of an alpha particle, which consists of two protons and two neutrons. During alpha decay, the parent nucleus loses an alpha particle to become a different nucleus called the daughter product. The daughter product formed after alpha decay will have an atomic number that is two less and a mass number that is four less than the parent nucleus.
What is the product of radioactive decay called?
Product of radioactive decay 42He is an alpha particle
What daughter product remains after the alpha decay of polonium-212?
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.
Is alpha decay the same as alpha radiation?
No. Decay is the process, radiation is the product.
Which daughter element is produced from the alpha decay of americium 241?
The alpha decay of americium-241 produce neptunium-237.
What is the product of alpha decay?
plutonium-239
What is the equation for alpha decay of Thorium?

What is the first decay product of uranium upon alpha decay?
It is thorium 234.
What is the product of radioactive decay HE called?
An alpha particle
In alpha decay is the atomic number of the daughter nucleus equal to the atomic number of the isotope undergoing decay?
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.
What is the daughter element produced from the alpha decay of 217 87 fr?
The daughter element produced from the alpha decay of ^217_87 Fr is ^213_85 At (Astatine). In alpha decay, the parent atom loses an alpha particle (two protons and two neutrons), resulting in the transformation into a new element with a lower atomic number.
What is the product of radioactive decay 42 He called?
An alpha particle
