# Is the following nuclear equation balanced?

## $\frac{226}{88} R a \to \frac{222}{86} R n + \frac{4}{2} H e$

Yes

#### Explanation:

An alpha particle is the equivalent of an atom of helium. So this means that when an alpha particle is ejected from the nucleus of an atom, a mass number of 4 and an atomic number of 2 is lost.

226 - 4 = 222
88 - 2 = 86

The equation is, therefore, balanced.
