Question

Write the equation that shows how radium 226 decays to give an alpha particle and another element?

Answer 1

Ra226 ---> He++ + Rn222, maybe. The previous answer may be incorrect because the answer had 4He, which is actually 16 n and p, not the four nucleids of a single helium atom. But given Answers Yahoo cannot do super/subscripts, it's hard to tell what the anwerer meant.

I answer "maybe" because many decays are multiple steps and end with stable elements. For example, Uranium decay eventually ends up as a lead (Pb) isotope. In the case of Ra to Rn (radon), there are a lot of things going on other than just the expulsion of one alpha particle. [See the source.]

Answer 2

226 Ra --> 4He + 222Ra
